Q.

Name two quantities that vary periodically at a place in air as a sound wave travels through it.

Q.

Q. A strong transverse pulse created at one end of a string is observed to complete 5 up and down journey along its length before fading out. The length of the string is 8m and the pulse takes 20 seconds to complete these journeys. What is the speed of the pulse through the string?

Q.

Q. State two differences between sound waves and light waves.

Q.

Can a transverse wave be produced inside water or gas ?

Q.

What is an electromagnetic wave?

Q.

Explain the term waves.

Q.

Define a wave. What are the two broad types of waves?

Q. Transverse waves cannot travel through

1. An iron rod
2. Hydrogen gas
3. A stretched nylon string
4. Lubricating oil

Q.

A 12 m long rope is tightly stretched between two points. A pulse generated in it travels forward and backward in 4 seconds. Calculate the speed of the pulse

Q. Give the differences between a transverse wave and a longitudinal wave.

Q. The waves in which the particles of the medium vibrate in a direction perpendicular to the direction of wave motion is known as:

1. propagated waves
2. transverse wave
3. stationary waves
4. longitudinal waves

Q. A man generates a symmetrical pulse in a string by moving his hand up and down. At t=0 the point in his hand moves downward from mean positoon. The pulse travels with speed of 3 m/s on the string and his hand passes 6 times in each second from the mean position. Then the point on the string at a distance 3 m will reach its upper extreme first time at time t=n/12. Then find n?

Q.
