Does the speed increase when a wave is reflected?
No, the speed of a wave does not change when it is reflected. The speed of a wave is determined by the medium through which it is traveling and remains constant regardless of reflection.
How is reflection of light different from refraction of light?
Reflection involves the bouncing back of light when it hits a surface, following the law of reflection that the angle of incidence equals the angle of reflection. Refraction, on the other hand, is the change in direction of light when it passes from one medium to another, caused by the change in speed of light.
Why do waves change speed?
Waves change speed when they move from one medium to another with a different density or elasticity. The change in speed is due to the wavefronts interacting differently with the particles in the new medium, causing a change in the wave's velocity. This can result in refraction, reflection, or diffraction of the wave.
Is The greater the change in speed the less the light wave is reflected?
No, the greater the change in speed of light when it enters a new medium, the more it tends to be reflected at the interface between the two mediums. This reflection is known as refraction, and the angle of refraction is determined by the change in speed of light.
What is the meaning of reflection and refraction?
Reflection is the bouncing back of light or sound waves when they hit a surface, changing direction but not entering the surface. Refraction is the bending of light waves as they pass from one medium to another medium with a different density, causing a change in speed and direction.
A wave changes directions when its speed changes This is called?
Reflection, or refraction, depending on what causes the change in direction.

What causes the bending of light in reflection?
The bending of light in reflection is caused by the difference in the speed of light in the two different mediums (air and a denser material) at the interface. This change in speed leads to refraction, resulting in the bending of light rays at the boundary.
What is the difference between reflection and refraction?
Reflection occurs when light bounces off a surface, while refraction happens when light passes through a medium and changes direction due to a change in speed. In reflection, the angle of incidence is equal to the angle of reflection, whereas in refraction, light bends towards or away from the normal depending on the change in speed between the two mediums.
What is the difference between refraction and reflection?
Refraction occurs when light changes speed and direction as it passes from one medium to another, such as from air to water. Reflection, on the other hand, is when light bounces off the surface of a material, like a mirror, and changes direction. Refraction involves a change in speed and direction, while reflection involves a change in direction only.
The bending of light from one material to another is?
called refraction, which occurs due to a change in the speed of light as it passes from one medium to another. This change in speed causes the light rays to change direction, resulting in the bending of light.
What is the difference between Sound Reflection and Sound Refraction?
Sound reflection occurs when sound waves bounce off a surface, changing direction but not speed. Sound refraction occurs when sound waves change speed and direction as they pass from one medium to another with different acoustic properties, such as air to water.
What happened to the speed of sound in air in closed room?
Nothing!! It remains same. In a closed room, if it is long enough, you may experience an echo. That is reflection of sound. But speed of sound does not change.
