Water waves are able to carry objects in the direction they are moving only - if the waves are very large. if the object is very light. where the water meets the beach. where the water is the deepest.

A piano tuner uses a 512-Hz tuning fork to tune a piano. He strikes the fork and hits a key on the piano and hears a beat frequency of 5 Hz. He tightens the string of the piano, and repeats the procedure. Once again he hears a beat frequency of 5 Hz. What happened?
Early Doppler shift experiments were conducted using a band playing music on a train. A trumpet player on a moving railroad flatcar plays a 320-Hz note. The sound waves heard by a stationary observer on a train platform hears a frequency of 350 Hz. What is the flatcar’s speed in mph? The temperature of the air is TC=22C .
Light can pass easily through water and through air, but light will reflect from the surface of a lake. What does this tell you about the speed of light in air and in water?
Two point on a wave that are at half-wavelength apart are …….…. degrees out of phase with each other.
A set of water waves travels at 20. 0 m/s , and 4.0 waves pass you in 2.0 s. What is the wavelength of the waves? 2.5 m O 10 m O 0.20 m O 5.0 m
You measure water depth using sonar. The sound wave your ship sends out takes 4 seconds to return to the ship. You know that the speed of sound in the waters around you is 1500 m/s. What is the water depth beneath your ship? 12,000 m O 6000 m 3000 m 1500 m
You can hear the sound from a person talking on your right in both ears because (A) sound diffracts around an obstacle in its path (your head). (B) of constructive interference of the sound waves around your head. (C) of refraction of sound waves when they strike your right ear. (D) sound waves are pressure waves that exert a force on your ear drum.
A child sits on a rock and notices that 3 wavelengths crash ashore in 45 seconds. a) What is the frequency of the waves crashing ashore? b). What is the period of the waves in this scenario?
Two sound waves of the same frequency can interfere, but, in order to produce beats, the two sound waves must be of different frequencies. Why?
Two waves, one traveling in water and another traveling in air, have the same frequency and the same wavelength. The speeds of the two waves are different because they are in different mediums the are the same because they have the same wavelegth and frequency are same in magnitude but opposite in direction because sound has a harder time going through water are impossible to determine without knowing the densities and temperatures of the two mediums.
The reason you can hear around Marge's hairdo is: The wavelength of sound is much longer than the obstacle's size O Sound cannot diffract because it is a transverse wave O The wavelength of sound is comparable to the obstacle's size Sound cannot diffract because it is a longitudinal wave
Determine the frequency of a sound wave in air at 20 degrees C with a wave length of 1cm. I think that f = # of waves divided by t but I'm not sure how to set that up with what's given
