The formula for the metric system is: 10dm = 1m = 100cm = 1000mm
How many billionths of a meter is that? nanometer is the answer.
The light that we can see is between _____ nanometers. 400 to 700 nanometers
is the answer.
That colour whose wavelength is the longest moves the fastest, bends the least,
and has the least energy? - ANSWER Red
That COLOUR whose wavelength is the smallest moves the slowlyest, bends
the most, and has the most energy? — ANSWER Violet
UVA rays have a wavelength of _______ nanometers and are absorbed by the
_______. -- ANSWER (315-400), a clear lens
The ________ absorbs UVB rays from ________ nanometers up. — ANSWER
(275–330), cornea
Sunlight's UVC rays are absorbed by the ______ and don't usually hurt the eyes.
— WHAT IT IS Atmosphere
Light waves in infrared are longer than light waves in red. - LONGER
ANSWER
How do you figure out how fast light moves through a different substance? -
The answer is n = c/v.
Figure out what n = c/v means. The index of refraction is the speed of light in
vacuum divided by the speed of light in the new medium.
What four things happen when a light ray hits a different substance? -
ANSWER a. Some light will bounce back from the edge.
