Which of the following factors influences the speed of a wave? i. the type of wave ii. the amplitude of the wave iii. the medium in which the wave travels

The correct answers are (I) and (III).

Explanation:

The expression for the relation between the speed of the wave and the frequency is as follows;

Here, f is the frequency and is the wavelength.

The speed of the wave depends on the medium in which the wave travels.

It depends on the type of wave but it does not depend on the amplitude of the wave.

For example, the speed of the sound wave is more in the solid medium in comparison to the liquid and gaseous medium as the solid medium is more dense. Here, the particles are more closer.

The speed of light is more than the speed of the sound. Light is transverse wave whereas sound wave is longitudinal wave.

Therefore, the factors which influence the speed of a wave are as follows;

the type of wave (II )and (III) the medium in which the wave travels.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
