What are the conditions for propagation of wave?

conditions). For the transmitted wave to match the incident wave at the boundary, the direction of propagation of the transmitted wave must be closer to perpendicular. When the direction of propagation changes, the wave is said to refract.

What is the medium of wave propagation?

A medium is the substance through which a wave can propagate. Water is the medium of ocean waves. Air is the medium through which we hear sound waves. The electric and magnetic fields are the medium of light.

How do the properties of a medium affect the propagation of electromagnetic waves passing through it?

The properties of materials affect the speed of moving waves, even for waves that don’t need a medium, like light waves. Light moves a little slower when it isn’t moving through a vacuum because the medium slows it down. And the speed of sound in water isn’t the same as the speed of sound in air.

What is necessary for elastic wave propagation?

If a material has the property of elasticity and the particles in a certain region are set in vibratory motion, an elastic wave will be propagated.

Does wave need medium?

Matter that waves are traveling through is called a medium. Sound waves cannot travel in the vacuum of space because there is no medium to transmit these mechanical waves. Classical waves transfer energy without transporting matter through the medium.

What happens to the medium when a wave moves?

Q: How do the particles of the medium move when a wave passes through them? A: The particles of the medium just vibrate in place. As they vibrate, they pass the energy of the disturbance to the particles next to them, which pass the energy to the particles next to them, and so on.

What are the properties of medium?

Essential properties of a medium for the propagation of mechanical waves:

• (i) Elasticity: For the particles to return to their mean positions after being disturbed, the medium must possess elasticity.
• (ii) Inertia: The medium must possess inertia or mass so that particles can store kinetic energy.

What is propagated in a wave motion?

wave motion, propagation of disturbances—that is, deviations from a state of rest or equilibrium—from place to place in a regular and organized way. Most familiar are surface waves on water, but both sound and light travel as wavelike disturbances, and the motion of all subatomic particles exhibits wavelike properties.

What are elastic properties of medium?

Elastic properties relate to the tendency of a material to maintain its shape and not deform when a force is applied to it. A material such as steel will experience a smaller deformation than rubber when a force is applied to the materials.

Do all waves require a medium to propagate explain?

Do all waves require a medium to travel? Explain. No, electromagnetic waves do not require any medium to propagate. No, mechanical waves do not require any medium to propagate.

Which waves do not need a medium to propagate?

Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.

When the motion of the particles of a medium is transverse to the direction of propagation the wave being transmitted is called a?

Answer: When the motion of the particles of a medium is parallel to the direction of propagation, the wave being transmitted is called a: longitudinal wave.
