Here are the physic hw questions Dizzy.

1. Periodic waves are produced by a wave generator at the rate of one wave every 0.5 seconds. What is the period of the wave?
2. Write an equation that correctly relates the speed v, wavelength lambda, and period T of a periodic wave.
3. If the frequency of a sound wave is 440 cycles per second, what is its period?
4. A sound wave travels at 340 meters per second. After 0.5 seconds, how far from the source of the wave has the wave traveled?
5. Sound waves with constant frequency of 250 H are traveling through the air at STP. Determine the wavelength of the sound waves.
6. What total distance will a sound wave travel in air in 3 seconds?
7. A sound wave is produced by a musical instrument for 0.40 seconds. If the frequency of the wave is 370 Hz, how many complete waves are produced in that time period?
8. New York’s 300-m high Citicorp Tower oscillates in the wind with a period of 6.80 s. Calculate its frequency of vibration.
9. While watching ocean waves at the dock of the bay, Otis notices that 10 waves pass beneath him in 30 seconds. He also notices that the crests of successive waves exactly coincide with the posts that are 5 meters apart.

                a.  What is the period of the ocean waves?

                b.  What is the frequency of the ocean waves?

                c.  What is the wavelength of the ocean waves?

                d.  What is the speed of the ocean waves?

  10.  A wave vibrates back- and -forth three times each second, and its wavelength is 2 meters.

               a.  What is its frequency? 

               b.  What is its period?

               c.  What is its speed?
