Which is bigger angle of incidence or reflection?
In this case, for light from the object to reflect off the mirror and travel to the eye, the light would have to reflect in such a way that the angle of incidence is more than the angle of reflection.
What happens when the angle of incidence is 90?
If the angle of incidence is 90 degrees, then the angle of reflection will also be 90 degrees. However, an angle of incidence of 90 degrees means that the wave is parallel to the surface it’s incident on. The wave will never come in contact with the surface since they are parallel to each other.
What happens when the angle of incidence is 90 degrees?
– The angle of reflection is equal to the angle of incidence, therefore, when a ray strikes the mirror at 90 degrees, the ray reflects back in the opposite direction on the same path, that is at 90 degrees.
Can angle of reflection exceed 90 degrees?
It is defined to be like this: the angle of the ray made with the normal of the surface of the object. So in any case, the angle of incidence and the refraction cannot exceed 90 degrees, since if you exceed 90 degrees, the incident light ray will be actually angle of refraction and vice versa.
What is the angle of incidence if the reflected ray is at an angle of 90 degrees?
What is the angle of incidence of a ray if the reflected ray is at an angle of 90 to the incident ray? Ans. The angle of incidence ray will be 45°.
When a light ray makes an angle of 90?
Refraction is the process of bending of light as it moves from one medium to another. When light ray from air in incident to a glass slab at any angle except 90 degrees, refraction occurs and the light ray bends towards the normal.
What is the angle of refraction when the angle of incidence is 30 degree?
The angle of refraction is 19.27°. Explanation: This can be determined using Snell’s law which states: Refractive index = sin i/sin r ( where i is the angle of incidence and r is the angle of refraction).
What will be the angle of deviation if the angle of incidence is 40 degree?
Answer. The graph of angle of deviation vs angle of incidence is a U shape. The fact that the angle of deviation is the same for these two rays means that a ray which is incident at 40 degrees to the normal will emerge at 60 degrees to the normal. This allows us to find the refractive index.
