What is the Doppler Effect?
When the frequency of a wave is shifted upwards.
When two waves of the same frequency and speed travells in opposite directions.
The difference between the observed frequency and the actual frequency.
If a moving ambulance is emitting sound waves and is approaching a stationary observer, how will the frequency be shifted?
Increased and shortened.
Increased and extended.
Decreased and shortened.
Decreased and extended.
Is the Doppler equations straightforward?
Is the Doppler Effect common to all waves?
What must be fulfilled in solving problems about electromagnetic waves?
v>>C
V<<C
V=C
Is the actual frequency denoted as f ' ?
If a moving source is moving away from the observer is the sign in the equation positive?
If the observer is moving away from a stationary source is sign in the equation positive?
