Speed of wave depends mainly on four factors. These factors are wavelength, frequency, medium and temperature.
We know from laws of refraction, when a wave travels from rarer to denser medium, the speed of wave slows down. And when it travels from denser to rarer, it speeds up.
The relation of speed of wave with its wavelength and frequency is given by the following:
The speed of a wave in a particular medium remains constant. A higher frequency wave has shorter wavelength.
The speed of a wave also varies with temperature in a given medium. temperature affects the density of the medium and vibrations of the medium particles. Higher the temperature, higher is the speed of wave.
The factors that affect the speed of a wave are wavelength and medium. The correct option is B.
Wavelength and the characteristics of the medium a wave travels through are the two key parameters that affect a wave's speed.
Wavelength is the separation between successive wavepoints, and medium is the substance or material through which the wave is travelling, such as air, water, or solids.
The speed of the wave typically decreases as the wavelength rises. Additionally, the densities, compositions, and properties of various media can vary, which has an impact on how quickly a wave can go through them.
For instance, sound waves move through the air more quickly than they do through water. In disciplines like physics, acoustics, and communications, having an understanding of these elements is essential.
Thus, the correct option is B.

(a) State three other lengths at which this pipe will resonate with the 384-Hz tuning fork. Explain / show your
reasoning​
Answer:
Three other length for which resonance will occur is 66 cm, 110 cm and 154 cm
Explanation:
As we know that the length of the pipe is 22 cm
Now let say it is in 1st harmonic state so we have
so we have
So we have
For N = 1
For N = 2
For N = 3
