5th SWE Review- Waves

The speed of a transverse wave in a string is 10 meters per second. If the frequency of the source producing this wave is 2.0 hertz, what is the wavelength of the wave, to the nearest tenth of a meter?

• 10
• 5
• 4
• 8

A police car traveling at a speed of 30.0 meters per second with its sirens on blast. As the police car approaches a stationary pedestrian, the pedestrian notices that the frequency is getting higher. What phenomena of waves is causing this?

• refraction
• interference 
• reflection
• Doppler effect

What is this called?

• refraction
• reflection
• reconstroction
• retraction

What happens when light hits a mirror?

• it makes a color
• it reflects
• it makes a rainbow
• it passes through
