Basics of Optics Review

​ (a)   do not require a medium.​

• transverse waves
• longitudinal waves

For longitudinal waves, the opposite of compression is

What's between radiowaves and infrared?

Match the units!

Groups:

(a) Frequency Units

,

(b) Wavelength Units

,

(c) Speed of light units

• Hz

• s^-1

• m/s

• (m/s) / (s^-1)

• m

Both wave A and wave B are types of electromagnetic radiation. If wave A has a greater frequency than wave B, then wave A must also have ​ (a)   than wave B.

• a smaller wavelength
• a greater wavelength
• the same wavelength

• Planck's constant

• height of the wave

• A constant that is equal to 1 in a vacuum

• The speed of light
