When an angle of incidence is 45 degree then the angle of reflection is?

90o
The correct answer is 90o. According to the first law of reflection of light, if the angle of incidence is 45 degrees then the angle between the reflected ray and the incident ray will be 90 degrees. ⇒ i + r = 45 + 45 = 90°.

What happens when angle of incidence is 45?

A ray of light may approach the boundary at an angle of incidence of 45-degrees and bend towards the normal. Of the three boundaries in the diagram, the light ray refracts the most at the air-diamond boundary.

What would be the angle of reflection if the incident ray is making an angle of 42 with the reflecting surface?

Hence the angle of reflection is equal to 0 degrees.

What is the angle of deviation for a ray which incident with an angle 45 (@) on the plane mirror?

150∘
(D) From the laws of reflection, the angle of incidence is equal to the angle of reflection. Then the sum of the angle of incidence and the angle of reflection gives the angle between the incident light ray and the reflected light ray. The angle of deviation of a light ray reflected by a plane mirror is 150∘.

When the angle of incidence is 50 degrees then the angle of reflection is?

the angle of reflection is always the same as the angle of refraction so for a ray hitting at 50, it will reflect to at 50 degrees.

What is the refractive index of a medium if the angle of incidence is 45 and angle of refraction is 30?

The refractive index of the material is 1.41.

What will be the angle between the incident ray and reflected ray if the angle of reflection is 40 degree?

Explanation: If the angle between the incident ray and mirror is 40 degree , then the angle of incidence will be 50 degree. Then the angle of reflection will 50 degree ( angle of incidence = angle of reflection).

What angle will the reflected ray make with the mirror if the angle of incident is 40?

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. Hope this helps.

What is the angle of incidence of a reflected ray?

The angle of incidence is measured from the normal to the mirror at the point where the ray strikes the mirror. Here the angle of incidence = 90–45 = 45 deg. So the reflected ray is at 45 deg, both from the normal to the mirror as well as the plane of the mirror.

What is the angle of reflection of a 45 degree mirror?

Here the angle of reflection is 75 deg measured from the normal to the mirror.. The angle of reflection will equal the angle of incidence. So a 45 degree angle of incidence will yield a reflected angle of 45 degrees.

How do you find the angle of incidence of a mirror?

Draw a normal at the point of incidence to the first mirror; measure the angle of incidence (45 degrees); then draw a reflected ray at 45 degrees from the normal. Repeat the process for the second mirror.

What is the angle of reflection on a 40 degree angle?

Your angle of incidence is 40°, so your angle of reflection is also 40°. Total turn is therefore: 180 – 40 -40 = 100 degrees. Early symptoms of spinal muscular atrophy may surprise you. Signs of spinal muscular atrophy can be easily ignored.
