Different density of objects
When a wave travels from one medium to another with a different speed or density, it causes the wave to bend. This change in speed and direction is due to refraction, where the wave changes its angle as it crosses the boundary between the two mediums.
Refraction of a wave occurs when it changes direction as it passes from one medium to another with a different speed, due to a change in its velocity. This change in velocity causes the wave to bend at the boundary between the two mediums. The amount of bending depends on the change in speed and the angle at which the wave enters the new medium.
Refraction phenomenon Typically, the change in wave speed in the material causes the change in direction.
Reflection, or refraction, depending on what causes the change in direction.
Longitudinal wave
Waves change speed and direction when they encounter changes in the medium through which they are moving. This can be due to variations in the density, temperature, or composition of the medium. The interaction causes the wave to refract, reflect, or diffract, leading to changes in its speed and direction.
A longitudinal wave causes its medium to oscillate in the same direction as the wave travels. This means that the particles of the medium move back and forth parallel to the direction of wave propagation. Examples of longitudinal waves include sound waves and seismic waves.
When a wavefront changes direction, the speed of the wave remains the same. However, the direction of the wave's velocity vector changes as it propagates through different mediums or encounters obstacles.
When a wave moves from one medium to another, its speed changes due to the different properties of the new medium. This change in speed causes the wave to bend, a phenomenon known as refraction. The amount of bending depends on the change in speed and the angle at which the wave enters the new medium.
Waves change direction as they near shore due to the interaction between the wave front and the sea bottom. This interaction causes the wave to slow down and bend, resulting in the wave refraction. Refraction causes the wave energy to focus on headlands and disperse in bays, affecting wave direction.
False. A transverse wave causes its medium to move perpendicular to the direction the wave travels. This means that the particles of the medium move up and down or side to side as the wave passes through.
Direction. When a wave is reflected from a mirror, its direction changes according to the law of reflection, which states that the angle of incidence is equal to the angle of reflection.
