60 degrees??Orodruin said:
Why would it be 50 degrees?Muhammad Danish said:
Sorry I mean't 60 degrees, since 90-30 = 60Orodruin said:
Yes, the incident angle is the angle between the surface normal and the ray, not between the surface itself and the ray.Muhammad Danish said:
Thanks a lot for pointing that mistake out. I was making the same mistake in many questions like that.Orodruin said:
The formula for calculating the angle of reflection is "angle of reflection = angle of incidence". This means that the angle at which a light ray bounces off a surface is equal to the angle at which it originally hit the surface.
The speed of light is related to the formula for refraction by the refractive index, which is a measure of how much the speed of light is reduced when passing through a certain medium. The formula for refraction is "sin(angle of incidence)/sin(angle of refraction) = speed of light in first medium/speed of light in second medium".
Yes, the formula for reflection and refraction can be used for all types of waves, including light, sound, and water waves. This is because all waves exhibit the same behavior when interacting with surfaces and passing through different media.
The angle of incidence directly affects the angle of refraction through Snell's law, which states that the ratio of the sines of the angles is equal to the ratio of the speeds of light in the two media. As the angle of incidence increases, the angle of refraction also increases, resulting in a greater change in direction for the light ray.
The critical angle is the angle at which light is refracted along the surface of a medium, rather than passing through it. It is significant because it determines whether total internal reflection will occur, and is dependent on the refractive indices of the two media. This phenomenon is used in various applications, such as in fiber optics and prisms.
