It is simply the transfer of energy from any source to a distant receiver without the transfer of matter between the two points. 2. Moving a slinky up and down produces a transverse wave…when its pushed and pulled it produces a longitudinal wave. 3. The energy returns to where it started. 4. 5. Electrons in glass have a natural vibration frequency in the ultraviolet range. Because of this, when UV light tries to pass through the glass it has too many collisions with the glass’ electrons and ultimately giving up its energy as heat, making glass opaque to UV light. But at lower frequencies such as visible light, there aren’t as many collisions and the light passes through the glass, making it

Unformatted text preview: transparent. 6. Polarizing sunglasses actually eliminate some of the light coming in (usually horizontally vibrating light). Regular sunglasses just dim all light down, no elimination though. 7. It absorbs light, turns it into heat, and keeps you warm. 8. No. Black is the absence of all color and white is the fulfillment of all color. 9. Violet has the highest energy of visible light. A black light looks kind of violet, but its ultra violet and the rays are damaging to our skin (UV light causes sun burn, but it doesn’t have to be from the sun). 10. The road is absorbs all the lights energy and turning it into heat, whereas the window pane only absorbs the heat/energy from light with a frequency higher than visible light (UV and above)....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
