Using the law of reflection of light,
Angle of incidence = angle of reflection = 40°
. Hence the angle of reflection is 40°, which means that the reflected ray will make an angle of 40° with the normal to the reflecting surface.
When a ray of light strikes a plane mirror at an angle of 15 degree with the mirror what will be the angle through which the ray get deviated?
Here since the light ray strikes a plane mirror at an angle of 15∘ with the mirror. So, the correct answer is “Option
B
”. Note: According to the law of reflection of light: the angle of incidence, the angle of reflection and the normal to the mirror all lie on the same plane.
Are of light strikes a plane mirror at an angle of 40 degree to the mirror surface What will be the angle of reflection?
A ray of light strikes a plane mirror at an angle of 40° to the mirror surface. What will be the angle of reflection? Now, we know that according to the law of reflection, the angle of incidence is equal to the angle of reflection. Therefore, the angle of reflection will be
50°
.
Are of light is incident normally on a plane mirror what will be the angle of incidence?
When the light ray is incident normally on the plane mirror then by using laws of reflection angle of incidence is equal to angle of reflection. Hence, as the angle of incidence is
zero degree
angle of reflection is zero degree. Thus, reflected ray will reflect back in same path as that of incident ray.
What happens when a light ray hits a plane mirror at an angle of 30 degrees to the mirrors axis?
Also, when light is reflected from a mirror,
it bounces off at the same angle in the opposite direction from which it hit
. For example, if the light hits a flat or “plane mirror” at a 30-degree angle from the left, it will bounce off at a 30-degree angle to the right.
What is the angle of incidence equal to when light is reflected?
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
.
Are of light strikes the mirror at an angle of 20 degree what is the angle of reflection?
Answer: Explanation: The ray of light strikes the mirror at an angle of 20 degree,it means it will make an angle of
70 degree (90-20) with
the normal. and also from the laws of reflection from mirror,we know that the angle of reflection is always equal to the angle of incidence.
What is the angle of deviation in a plane mirror at normal incidence?
The total angle between the straight-line path and the reflected ray is
twice the angle of incidence
. This is called the deviation of the light and measures the angle at which the light has strayed from its initial straight-line path. The deviation of a mirror is equal to twice the angle of incidence.
What are the values of angle of incidence I and angle of reflection R for normal incidence of light on a plane mirror?
Normal incidence implies,
i = 0°
. Hence, from the second law of reflection, r = 0°.
What is the angle of incidence of a light ray reflected off a plane mirror at an angle of 35 degrees to the normal?
Angle of incidence and angle of reflection are the angles that incident ray and reflected ray, makes with the normal (to the mirror), respectively. In this case, the angle of incidence is given as
35 degrees
, thus the angle of reflection is also 35 degrees.
What is the incident ray?
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.
When light is incident on a mirror at 30 degree from the normal at what angle does it reflect?
The incident ray will have an angle of reflection of 30 degrees (made with a surface normal to the mirror surface). The reflected ray will make an angle of
60 degrees
(90 – 30 degrees) with the mirror surface.
What is an angle of reflection equal to?
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.
What is the formula for angle of incidence?
| Angle of Incidence (degrees) Angle of Refraction (degrees) | 85.0 48.5 |
|---|
What is the angle of reflection of the angle of incidence is 30?
What is the angle of reflection if the angle of incidence is 30 degree? Explanation: The angle between the mirror and the incident ray is 30 degrees. The sum of the angle of incidence and this angle (30) makes a right angle. So, the angle of incidence is
90 – 30 = 60 degrees
.
