Waves

The energy of a wave is proportional to:

1. Amplitude
2. Square of amplitude
3. Frequency only
4. Wavelength only

Beats are produced due to interference between two waves having:

1. Same frequency
2. Slightly different frequencies
3. Zero amplitude
4. Very high speed

The phenomenon of bending of waves around obstacles is called:

1. Reflection
2. Refraction
3. Diffraction
4. Polarisation

Standing waves are formed due to:

1. Reflection only
2. Interference of two waves travelling in opposite directions
3. Absorption of waves
4. Increase in frequency

The principle of superposition applies to:

1. Only light waves
2. Only sound waves
3. All linear waves
4. Only mechanical waves

The speed of sound is maximum in:

1. Vacuum
2. Gases
3. Liquids
4. Solids

The time taken by a particle to complete one oscillation is called:

1. Frequency
2. Wavelength
3. Time period
4. Velocity

The phenomenon in which two waves combine to produce a resultant wave is called:

1. Reflection
2. Interference
3. Refraction
4. Diffraction

A wave in which particles vibrate parallel to the direction of propagation is:

1. Transverse wave
2. Longitudinal wave
3. Surface wave
4. Electromagnetic wave

The distance between two consecutive crests of a wave is called:

1. Amplitude
2. Frequency
3. Wavelength
4. Time period

In a transverse wave, particles of the medium vibrate:

1. Parallel to wave direction
2. Perpendicular to wave direction
3. Randomly
4. Without motion

The relation between wave velocity, frequency and wavelength is:

1. v = fλ
2. v = f/λ
3. v = λ/f
4. v = f + λ

A wave is a phenomenon in which:

1. Matter is transferred from one place to another
2. Energy is transferred without permanent transfer of matter
3. Only particles move permanently
4. Mass is created and destroyed
