What happens when a ray of light passes through the centre of curvature of a lens?

What happens when a ray of light passes through the centre of curvature of a lens?

So, any light ray that passes through the center of curvature of a mirror is always reflected through the same path. Note: This is also true for lenses, when the light passes through the center of curvature of a lens (convex or concave) it is not refracted and passes straight through the lens.

How do you think a light ray passing through the centre of curvature will behave when it hits a concave or a convex mirror?

Any incident ray traveling parallel to the principal axis on the way to a concave mirror will pass through the focal point upon reflection. Any incident ray passing through the focal point on the way to a concave mirror will travel parallel to the principal axis upon reflection.

What will happen when an incident ray pass through the center of curvature of a concave mirror?

Expali why a ray of light passing through the centre of curvature of a concave mirror, gets reflected along the same path. (focus/centre of curvature) travels back along its original path after reflection.

When an incident ray passes through centre of curvature of a spherical mirror then the reflected ray will?

We know that when an incident ray that passes through the center of curvature of the mirror is reflected back along its own path as it is normally incident on the mirror. Hence the reflected ray will retrace its path.

Why does a ray of light passing through optical centre goes Undeviated?

Complete answer: The rays passing through the optical centre of the lens pass undeviated. This is due to the fact that it travels through the optical centre perpendicular to the lens’s curved surface. As a result, the angle of incidence is zero, and the angle of refraction is zero as well.

Why does a ray of light passing through C goes Undeviated?

The rays passing through the optical centre of the lens pass undeviated. A ray of light going through the optical centre experiences no refraction, meaning it passes through the centre without deviating. This is due to the fact that it travels through the optical centre perpendicular to the lens’s curved surface.

What happens when a light ray passes through the focal point and then reflects off of a convex mirror?

Any incident ray traveling towards a convex mirror such that its extension passes through the focal point will reflect and travel parallel to the principal axis. Any incident ray which is directed towards the center of curvature of the mirror is reflected back along its own path.

In which direction do the reflected rays travel when you shine rays of light parallel to the principal axis onto a convex mirror?

Light rays parallel to the optical axis are reflected from the surface in a direction that diverges from the focal point, which is behind the mirror (Figure 5). Images formed with convex mirrors are always right side up and reduced in size.

What happens to the light ray incident on a concave mirror parallel to its principal axis?

Any incident ray traveling parallel to the principal axis on the way to the mirror will pass through the focal point upon reflection. Any incident ray passing through the focal point on the way to the mirror will travel parallel to the principal axis upon reflection.

When a ray of light is incident normally on the surface of a plane mirror the angle of incidence is?

0°
Q7) A ray of light falls normally on a plane mirror. What is the angle of incidence? Solution : Angle of incidence is 0°.

Which part of a spherical mirror is situated midway between the center of curvature and the vertex?

focal point
Midway between the vertex and the center of curvature is a point known as the focal point; the focal point is denoted by the letter F in the diagram below. The distance from the vertex to the center of curvature is known as the radius of curvature (represented by R).

Why a ray of light passing through the centre of curvature?

Why a ray of light passing through the centre of curvature of concave minor gets reflected along the same path? The reason for light falling on the centre of curvature gets reflected back along the same path is due to the angle of incidence and the angle of reflection lie along the normal for a concave mirror.

How does the ray of light travel through a concave mirror?

The ray of light passes through the centre of curvature of a concave mirror it strikes the mirror along the normal ray It incidences on to the mirror at an angle of 90 degrees. Hence the incident ray coincides with the normal. Hence the angle of reflection tends to zero degree, thus ray of light retraces its path.

Why is a ray of light incident normally to a mirror?

>> Explain why a ray of light Explain why a ray of light passing through the centre of curvature of a concave mirror gets reflected along the same path after reflection. This is because the angle of incidence is 0 ∘ . That is the ray passing through the centre of curvature is incident normally to the mirror.

Why are rays of light reflected along the same path after reflection?

Explain why a ray of light passing through the centre of curvature of a concave mirror gets reflected along the same path after reflection. This is because the angle of incidence is 0 ∘ . That is the ray passing through the centre of curvature is incident normally to the mirror. The angle of reflection should also be 0 ∘ .
