1. How is wave speed related to frequency and wavelength? 2. Does the frequency of a wave depend on the properties of the medium? 3. What happens to wavelength when speed is decreased? 4. What are two ways to decrease the speed of the wave (you can change the medium here, but how)?
When the source of a wave and an observer move either towards or away from each...
When the source of a wave and an observer move either towards or away from each other the observed frequency of the wave will be different from the frequency at which the wave is emitted. For example, if you are standing by the side of the road and a police car with a siren passes by, the frequency of the sound you hear will be higher when the car is moving towards you and lower when it is moving away...

A light wave traveling in a medium with index of refraction n1 is incident on another medium with index of infraction n2>n1. Which of the following is a true statement about the behavoir of light wave in a second medium. a. The speed of light wave remains the same as in the first medium b. The wavelength of the light wave remains the same as in the first medium c. The frequency of the light wave remains the same as...

How do the values for frequency, period, and wave speed compare? The frequency is the inverse of the period, and the velocity is equal to the wavelength divided by the period. Frequency and period are equivalent, and the speed of the wave is determined by the wavelength times the period. The velocity of a wave is equal to the frequency divided by the period. The speed of a wave is equal to the frequency times the period. The frequency measures...

2. A source is moving past a sound sensor in an unknown medium. The frequency detected in front of the source was 2700 cycles per second, and the frequency detected behind the source was 1300 Hertz. The object was clocked by a radar gun to be moving at 21 m/s. What is the speed of sound in the medium?
