Answer:
A
Explanation:
The amplitude of a wave is directly proportional to the energy it carries. Amplitude is the distance of displacement, by a particle of the wave, in the media in which it travels. The higher the energy in the wave the higher the amplitude and vice versa. The frequency and wavelength of the wave (which are dependent on the type of wave) remain unchanged even with the change in amplitude.
Some of the waves energy is always being dissipated as heat which will reduce the waves amplitude.
Those waves which carry energy in it in any form is known as waves energy, e.g. ocean waves, wind waves, etc.
Waves will carry energy in it and show their energy can be noticed in the form of their movement. When waves carry low amount of energy then they do not show much movement as compare to the waves which carry high energy. So, we conclude that wave energy is directly proportional to the amplitude, i.e. more energy results in more displacement of particle from their mean position in the medium.
Hence, option (a) is correct i.e. when amplitude reduces, some of the waves energy is always being dissipated as heat.
