Chemistry Music Video 12: What The Heck Is Light

This song explains how light is formed, what the different types of electromagnetic radiation are and the significance of bright-line spectra.  Lightning filmed June of 2007.  Music and lyrics copyright 2007 by Mark Rosengarten.  All rights reserved.

Lyrics:

Light, LIGHT!  It scares away the fright
Soothing incandescence in the middle of the night
No more bed at sunset, much to our delight
You know we all adore it, but what the heck is LIGHT?

Look at the electrons, all happy in their shells
Zipping right along, their life is pretty swell
Each one has their own amount of certain energy
And they will stay forever, if you let them be

But if you kick an atom squarely in the pants
The electrons get excited and will do their special dance
Some absorb the energy and move to higher shells
And leave behind blank places in the spots that once they dwelled

What goes up, must then come down is not a silly beast
When electrons fall back down, extra energy released
Whatever made them to proceed in their upwards flight
When they give off energy, its in the form of LIGHT!

The farther that they fall, the more power has the light
The shorter is the wavelength (the waves will be packed tight)
The higher is the frequency of wavelengths that will pass
Light is made of photons, which have no charge or mass!

Light, LIGHT!  It wows us with its might
Phosphorescent stars in the middle of the night
Ceiling constellations, much to our delight
You know we all adore it, but what the heck is LIGHT?

Light comes in many flavors, depends on energy
Only a slight range of light is light that we can see
From red to blue to violet, mnemonic we can give
Is easy to remember, it is ROY G BIV!

Light with lower energy starts with radio
Listen to your music anywhere you go
Radar has more energy, cops use it on their beat
Then comes infrared, which is given off with heat

Ultraviolet rays can cause sunburns at the lake
X-rays go through all but bone to see if theres a break
Finally, theres gamma rays, but they have so much juice
They go through almost everything if you set them loose.

Elemental atoms give off bands of colored light
Its called a bright-line spectrum because the lines are bright
Each elemental spectrum is different from the rest
Identifies what element you have in a test

Light, LIGHT!  It wows us with its might
Aurora borealis in the middle of the night
Glowing in the northern sky, much to our delight
Now you know the truth about that wondrous thing called LIGHT!

Lightning followed by thunder.

Unfortunately, I missed a very bright lightning clear strike by 1 second, but I managed to capture this one.  The sound was almost deafening.  Taken in Soran, Kurdistan region of Iraq.

Measuring the electromagnetic spectrum

You actually know more about it than you may think! The electromagnetic (EM) spectrum is just a name that scientists give a bunch of types of radiation when they want to talk about them as a group. Radiation is energy that travels and spreads out as it goes-- visible light that comes from a lamp in your house and radio waves that come from a radio station are two types of electromagnetic radiation.

Other examples of EM radiation are microwaves, infrared and ultraviolet light, X-rays and gamma-rays. Hotter, more energetic objects and events create higher energy radiation than cool objects. Only extremely hot objects or particles moving at very high velocities can create high-energy radiation like X-rays and gamma-rays.

The different types of radiation in the EM spectrum, in order from lowest energy to highest: 

Radio: Yes, this is the same kind of energy that radio stations emit into the air for your boom box to capture and turn into your favorite Mozart, Madonna, or Justin Timberlake tunes. But radio waves are also emitted by other things ... such as stars and gases in space. You may not be able to dance to what these objects emit, but you can use it to learn what they are made of.

Microwaves: They will cook your popcorn in just a few minutes! Microwaves in space are used by astronomers to learn about the structure of nearby galaxies, and our own Milky Way!

Infrared: Our skin emits infrared light, which is why we can be seen in the dark by someone using night vision goggles. In space, IR light maps the dust between stars.

Visible: Yes, this is the part that our eyes see. Visible radiation is emitted by everything from fireflies to light bulbs to stars ... also by fast-moving particles hitting other particles.

Ultraviolet: We know that the Sun is a source of ultraviolet (or UV) radiation, because it is the UV rays that cause our skin to burn! Stars and other "hot" objects in space emit UV radiation.

X-rays: Your doctor uses them to look at your bones and your dentist to look at your teeth. Hot gases in the Universe also emit X-rays .

Gamma-rays: Radioactive materials (some natural and others made by man in things like nuclear power plants) can emit gamma-rays. Big particle accelerators that scientists use to help them understand what matter is made of can sometimes generate gamma-rays. But the biggest gamma-ray generator of all is the Universe! It makes gamma radiation in all kinds of ways.

What Causes Color Blindness?

Some people in the world aren’t able to see many colors. The condition is called color blindness, but what exactly causes it?

“When Concetta Antico looks at a leaf, she sees much more than just green. ‘Around the edge I’ll see orange or red or purple in the shadow; you might see dark green but I’ll see violet, turquoise, blue,’ she said. ‘It’s like a mosaic of color.’”

New Outlook on Colorblindness
http://www.wsj.com/articles/SB10001424052970204349404578100942150867894
“For people who are colorblind, life involves little workarounds and big compromises alike.”

A Cure for Colorblindess

“I stood in the center of Times Square. Fiery orange flames and velvet purple sunsets five stories tall promised that I could stay Forever 21. Along with Vegas and Versailles, few spots in the world depend so heavily on the seductive power of colors. If I was going to see full color for the first time in my life, this was the spot to do it. I am colorblind, but in the last few years new sunglasses have promised to open me up to the world of color.”

Caucasian Boys Show Highest Prevalence of Color Blindness Among Preschoolers
http://www.sciencedaily.com/releases/2014/04/140403084243.htm
“The first major study of color blindness in a multi-ethnic group of preschoolers has uncovered that Caucasian male children have the highest prevalence among four major ethnicities, with 1 in 20 testing color blind.”

Color vision problems become more common with age, study shows
http://www.sciencedaily.com/releases/2014/02/140220102614.htm
“Abnormal color vision increases significantly with aging -— affecting one-half or more of people in the oldest age groups, reports a study.”
