The amount of the diffraction will depend on the wavelength of the incident wave as well as the size of the opening. The more increased the wavelength is, the bigger the diffraction is going to be. There are people who think that waves are fascinating especially when the wave breaks and it allows itself to be ridden by people through proper balance and body strength.
When a wave passes through a barrier, it automatically becomes diffracted by the size will always differ. There are some waves that are bigger than the others while there are also others that are not too evident. Waves can go through different obstacles and openings and the results will be different every time.
The amount of diffraction depends on the wavelength of the incident wave and size of the opening. Hence, the correct option is C.
Basically, diffraction tells how do the waves bend or change direction. And it is directly proportional to the size of the wavelength (denoted by lambda). That means, the longer the wavelength of the wave is, the larger the amount of diffraction will be. In short, we can say that And the possibility of the greatest diffraction occurs when the gap size is approximately same as the wavelength.
