For refraction, the general relationship is given by Snell's Law.
I think all EM waves refract AND reflect, however, this would be very hard to demonstrate in the lab because of the wavelengths (and materials) involved. ============================ Reflection of E&M waves is indeed difficult to demonstrate in the lab, except when you look at yourself in the lab's mirror. Refraction is also nearly impossible to demonstrate, unless you wear glasses. Refraction an reflection can be demonstrated in the lab with water waves, and with a bit of cleverness and innovation, with sound waves too.
Refraction occurs for any waves, where there's a change in the medium.
Both
Refraction is when light slightly bends because glass or water is in the way. This makes the object look bent or crooked. For example when you put a straw in a glass of water, the straw looks as if it were bent, but it really isn't. Reflection is when the light particles of an object bounce off of another object showing the same image. You can't see your reflection on all objects though.
It happens when light travels through a material that has a greater "optical density" (refraction index, really) than a bordering material, and when it touches the surface at an angle that is sufficiently flat.
In sound reflection, the angle of incidence is equal to the angle of reflection. This means that sound waves hitting a surface at a certain angle will bounce off and be reflected at the same angle on the other side of the surface.
Angle of Incidence is equal to Angle of Reflection.
Quick Answer:The angle of incidence is not equal to the angle of refraction.The angle of incidence is equal to the angle of reflection.Better Answer:(This answer applies to all waves, e.g. sound, ripples, earthquakes, but the answer is given in terms of light waves.)The angle of incidence never equals the angle of refraction except in the peculiar circumstance when there is an interface between two materials of exactly the same index of refraction.The angle of refraction is the direction of the wave exiting the surface and the angle of incidence is the angle entering the surface.These two angles are related by Snell's law and by Snell's law one would conclude that the index of the medium of the incident beam would be exactly the same as the index of the transmitted beam. In optical terms, it would mean the wave propagates as though there were no interface and the two mediums were actually the same medium. In that case, there would be no reflection as well.So, one does not expect this to happen, not because it can't, but because the wave travels through the surface as though the surface did not exist and that is both unusual and uninteresting.
Set up a sound source and a microphone on opposite sides of a smooth, hard surface. Emit a sound wave from the source and measure the angle of incidence and angle of reflection using a protractor. Repeat the experiment for different angles of incidence and observe that the angle of incidence is equal to the angle of reflection, confirming the law of reflection of sound.
When a sound reflects, it bounces off a surface and changes direction. The sound wave behaves similarly to light waves reflecting off a mirror. The angle of incidence is equal to the angle of reflection.
When a sound wave reflects off a hard surface, it bounces back towards the source. The angle of incidence (incoming angle) is equal to the angle of reflection (outgoing angle). This can create echoes and influence the overall sound in the environment.
The reflection is vibration because sound is equal to vibration
When sound waves hit a plane surface, they can be reflected, absorbed, or transmitted through the material. The angle of incidence will typically equal the angle of reflection, following the law of reflection. The material and texture of the surface will impact how much sound is absorbed or reflected.
bats and dolphins use sound refraction to hunt for food. the bat is blind so they have to use sound refraction.
Refraction of a sound wave occurs when it passes through media with different densities, causing a change in its speed and direction. This change in speed leads to the bending of the sound wave at the interface between the two media.
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.
Much of the sound will be reflected (the amount reflected will depend on the angle of incidence). If the angle of incidence is low enough, the sound will be completely reflected. The portion which is transmitted into the water, if any, will be refracted because of the difference in the speed of sound between air and water. Since the speed of sound in water is greater than the speed of sound in air, the sound will be refracted toward the surface of the water. Note that this is the opposite of what happens with light which has a slower speed in water than in air and is refracted away from the surface of the water.
