What is the Doppler Effect?

• A change in frequency due to the relative motion of a wave source and an observer

• When a wave overlaps with another wave

• When a wave bounces off of another object

• When a wave bends due to traveling through a different medium

An astronomer looks at a star in the night sky. Based on his calculations the star's light is shifting towards the color blue. What does this mean about the star?

• It's moving towards the astronomer

• It's moving away from the astronomer

What is Echolocation?

• The location of objects by reflected sound

• The location of sound source

• The sound of location interest

• The detection of sound in cave

The wave that oscillates parallel to the wave direction with compress and expanse motion?

• Longitudinal wave

• Transverse wave

• Sinusoidal wave

• Micro wave

What is Echo?

• It is the reflection of the sound waves

• It is the propagation of the sound wave

• It is the ultraviolet radiation reflection

• It is a sound made by transmitter

when one object, vibrating at the same natural frequency of a second object, forces that second object into vibration motion, it is called

• harmonics
• frequency
• amplitude
• resonance
