Transverse and Longitudinal Waves

Q.

Are electromagnetic waves- longitudinal or transverse

Q.

A wave transports energy and not matter. Justify this statement.

Q. Particles in longitudinal waves oscillate to the direction of wave motion.

1. perpendicularly
2. parallelly
3. diagonally

Q.

What is the difference between longitudinal, transverse and mechanical wave ?

Q.

1.do mechanical waves lose energy as they travel through a medium? Why/why not?

Q. State whether the given statement is True or False :Sound waves are transverse whereas light waves are longitudinal in nature .

1. True
2. False

Q.

Question 11
Lightning can be seen the moment it occurs. Paheli observes lightning in her area. She hears the sound 5 s after she observed lightning. How far is she from the place where lightning occurs? (speed of sound = 330 m/s).

Q.

Which travels faster than the other - sound or light?

Q.

A wave is a disturbance created in an elastic medium and it transfers matter from one place to another.

1. True

2. False
