Question
If an object is emitting sound and is moving through the air at the same time, which effect best
describes the change in wave frequencies that a stationary observer might hear?
Noise Effect
Decompression Effect
Doppler Effect
O Compression Effect
Why is the human eye so sensitive to the very narrow
and of visible light between about 570 nm
and 590 nm?
OBecause it is high contrast
OIt's a sign of danger
To take maximum advantage of the Sun's light
O To protect our eyes from the Sun.
An example of the Doppler Effect in action would be when...
A change in the mass of the sound wave.
O The energy transfer from sound to heat energy
O When someone dopplers the ball in baseball
The high pitch sound of a motorcycle approaching, followed by deepening of the sound after it passes
