2. Water
3. Steel
4. Space

Waves that travel perpendicular to the direction of vibrations are known as:

2. Longitudinal wave
3. Circular wave
4. None of these

Light waves are

1. Longitudinal
2. Transverse
3. Partly longitudinal, partly transverse
4. Sometimes longitudinal, sometimes transverse.

When a longitudinal wave travels through a medium, the particles of the medium show compression and Rarefaction. What happens when compression takes place in the medium?

1. The Density of the medium decreases.
2. The pressure of the medium decreases.
3. The molecules of the medium come closer to each other.
4. The Wavelength of the wave increases.

In which of the following media can non-mechanical waves travel?

2. In vacuum but not in a medium
3. In a medium but not in a vacuum
4. Neither in a medium nor a vacuum

Longitudinal waves are those ___.

In a medium, a mechanical wave travels. With the wave, which of the following quantities is moved from one point to another?

1. Mass
2. Speed
3. Density
4. Energy

A longitudinal wave is produced by the vibration of an object. It travels through a medium such as air by forming alternate regions of compression and Rarefaction of air molecules. As a longitudinal wave travels through air, the regions of compression and Rarefaction in it can be shown as:

A pulse is a wave:

1. Of high duration
2. Of short duration
3. Which travels in a vacuum only
4. Which travels in solids only

2. Transverse and Electromagnetic
3. Electromagnetic and Longitudinal
4. None

Sound waves are:

1. Longitudinal
2. Transverse
3. Partly longitudinal, partly transverse
4. Sometimes longitudinal, sometimes transverse.

Transverse waves have ________.

1. Crest
2. Trough
3. Rarefaction
4. Both a and b

Assertion: Sine and cosine functions are periodic functions.
Reason: Sinusoidal functions repeat their values after a definite interval of time.

1. Assertion is correct, the reason is correct; the reason is a correct explanation for assertion
2. Assertion is correct, the reason is correct; the reason is not a correct explanation for assertion
3. Assertion is correct, the reason is incorrect
4. Assertion is incorrect, the reason is correct
