Class 10 Physics- Unit 10- General Waves Properties-Solved Numericals

 

1. What is the wavelength of a radio wave broadcasted by a radio station with a frequency of 1300 kHz? Where 1K = 103, and the speed of the radio-wave is 3x 108 .

2. The waves moving in the pond have a wavelength of 1 .6 m, and a frequency of 0.80 Hz. Calculate the speed of these water waves.

3. If 50 waves pass through a point in the rope in 10 seconds, what are the frequency and the period of the wave? If its wavelength is 8 cm, calculate the wave speed. Explain the type of wave produced.

4. A slinky has produced a longitudinal wave. The wave travels at a speed of 40 cm/s and the frequency of the wave is 20 Hz. What is the minimum separation between the consecutive compressions?

5. Suppose a student is generating waves in a slinky. The student's hand makes one complete forth and back oscillation in 0.40 s. The wavelength in the slinky is 0.60m. For this wave, determine a. Period and frequency b. Wave speed

6. If 80 compressions pass through a point in spring in 20 seconds. Calculate the frequency and the period? If two consecutive compressions are 8 cm apart, calculate the wave speed.

7. Waves on a swimming pool propagate at 0.90 m/s. If you splash the water at one end of the pool, observe the wave go to the opposite end, reflect, and return in 30.0 s. How far away is the other end of the pool?

8.A simple oscillating pendulum has a length of 80.0 cm. Calculate its a. Period b. Frequency When g = 9.8 m s-2
