What happens if the angle of incidence is 0?

If the incident ray falls along the normal, the angle of incidence is 0 degrees, NOT 90 degrees. The angle is measured with the normal to the mirror and not with the plane of the mirror. Hence the angle of reflection is equal to 0 degrees.

Do the incident ray reflected ray lie on the same plane?

The INCIDENT ray,REFLECTED ray, REFRACTED ray and the NORMAL at the point of incidence all lie in the same plane. The plane is referred as plane of incidence.

What happens if angle of incidence is equal to angle of reflection?

The law of reflection states that the principle when the light rays fall on the smooth surface, the angle of reflection is equal to the angle of incidence, also the incident ray, the reflected ray, and the normal to the surface all lie in the same plane.

Are the angle of incidence and reflection always the same?

The angle between the surface normal and the reflected ray is known as the angle of reflection . The Law of Reflection says that for a specular (non-scattering) surface, the angle of reflection always equals the angle of incidence.

When a light ray enters into glass medium from water at an angle of incidence 0 degrees what would be the angle of refraction?

When a light ray travels along the normal, its speed changes in the second medium but the direction remains the same. Thus when the angle of incidence is zero degrees then the angle of refraction will also be zero degrees.

What would happen if a ray of light passes through air and into water at an angle of incidence of zero degrees?

This ray will refract, bending towards the normal (since the light is passing from a medium in which it travels fast into one in which it travels slow – FST). The ray does not refract upon exiting since the angle of incidence is 0-degrees (recall the If I Were An Archer Fish page).

Why incident ray reflected ray and normal are in same plane?

The angle of incidence is the angle between a ray incident on a surface and the line perpendicular to the surface at the point of incidence, called the normal. The angle of incidence is equal to the angle of reflection. The Normal, Incident ray, reflected ray lie on the same plane at the point of Incidence.

When can we see both incident and reflected ray?

Answer: There are two statements in the law of reflection: first one is that the angle between the incident ray and the reflected ray is always equal and the second one is that the incident ray ,the reflected ray, is normal and the point of the incident lies in the same plane.

When a light ray is reflected from a surface the ratio of the angle of incidence to the angle of reflection is?

The law of reflection states that the angle of reflection equals the angle of incidence—θr = θi. The angles are measured relative to the perpendicular to the surface at the point where the ray strikes the surface.

When light rays reflect off a plane mirror the angle of incidence?

The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.

Why does light reflect at the same angle?

Light interacts with the surface electrons in a material … it is the electromagnetic interaction that produces the reflection. Light is the result of lots and lots of photon interaction … light reflects with equal angles because that is the average of what the photons do.

Why is the incident ray equal to the reflected ray?

Answer: the law of reflection states that the reflected ray, the incident ray and the normal all lie in the same plane. therefore, the angle of reflection is equal to the angle of incidence.

What is the angle of incidence and reflection of a ray?

Similarly, angle of reflection is the angle made by the reflected ray with a normal drawn to the reflecting surface. angle of incidence = angle of reflection = 90 degrees. Thus, an angle of reflection of 90 degrees is caused by an incident ray that has an angle of incidence of 90 degrees.

What does an angle of reflection of 90 degrees mean?

An angle of reflection of 90 degrees means that the reflected ray travels along the surface. This is because the incident ray is also traveling along the reflecting surface. Hope this helps.

What is the incident ray of light?

An incident ray is a ray of light that strikes a surface. The angle between this ray and the perpendicular or normal to the surface is the angle of incidence. The reflected ray corresponding to a given incident ray, is the ray that represents the light reflected by the surface.

What is the law of reflection?

The law of reflection is that the angle of reflection is equal to the angle of incidence. This occurs for all situations. When a ray of light falls normal to the plane of the mirror, it is perpendicular or a 90 degree angle. Thus the reflected ray will come directly back from the mirror toward the source of light.
