Question

For a wave propagating in a medium, identify the property that is independent of the others

• A. Frequency
• B. Velocity
• C. Wavelength
• D. All the above options

Answer 1

The correct option is A

Frequency

Explanation for the correct option:

Option A:

1. When a wave propagates through a medium, the wavelength and the velocity reduces by a factor $\mu$(refractive index). Whereas, the frequency remains unaffected.
2. As frequency does not change when a wave propagates through a medium, it is independent of other factors.
3. Hence, this is the correct option.

Explanation for the incorrect options:

Option B:

1. As velocity is reduced by a factor of $\mu$when a wave propagates through a medium, it is dependent on $\mu$.
2. Hence, this is not the correct option.

Option C:

1. As the wavelength is reduced by a factor of $\mu$when a wave propagates through a medium, it is dependent on $\mu$.
2. Hence, this is not the correct option.

Option D:

1. As the frequency is independent of other factors, the given options cannot all be dependent on each other.
2. Hence, this is not the correct option.

Hence, option A is the correct option.
