PS05-3 DAY 1

The distance from the crest of one wave to the crest of the next wave is called:

• amplitude
• frequency
• wavelength
• medium

What are the units of frequency?

• m/s
• s
• Hz
• N

Which is a correct equation?

• wave speed = frequency + wavelength
• wave speed = frequency × wavelength
• wave speed = frequency ÷ wavelength
  

Which statement about the oscillations of light waves is correct?

• They are parallel to the direction of energy transfer
• They are perpendicular to the direction of energy transfer
• They rotate around the direction of energy transfer

Which statement about the oscillations of light waves is correct?

• They are parallel to the direction of energy transfer
• They are perpendicular to the direction of energy transfer
• They rotate around the direction of energy transfer

What is causing you to be able to see two sets of mountains in this picture? 

• refraction of light
• reflection of light
• transmission of light
• absorption of light

What is happening to the light waves as they hit the black object in the middle? 

• They are being reflected.
• They are being absorbed.
• They are being refracted.
• They are being transmitted.
