WebMar 11, 2024 · For some angle (the critical angle) the angle of refraction is 90 degrees. This is the situation where n 1 > n 2. For angles larger than the critical angle, light is reflected instead. The opposite situation is when light moves from air to water. In this case the light is refracted towards the vertical, and there is no critical angle and no ...

WebNov 25, 2015 · The critical angle comes into play when you consider where the peak of the wave is on the boundary between two mediums. If θ is the angle between the wave direction and the surface normal and v is the speed of the wave, this point travels at a speed csc ( θ) v. This makes sense: if θ = π / 2, the point at the boundary is just the wave speed. When light travels from a medium with a higher refractive index to one with a lower refractive index, Snell's law seems to require in some cases (whenever the angle of incidence is large enough) that the sine of the angle of refraction be greater than one. This of course is impossible, and the light in such cases is completely reflected by the boundary, a phenomenon known as total internal r… WebMar 31, 2024 · B. when the angle of incidence is greater than the critical angle . Explanation: As we know by law of refraction of light that. now here we know that total internal reflection only occurs when light travel from denser medium to rarer medium. so here. now if angle is critical angle then at that point angle of refraction must be 90 degree is a task in a business process
