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 will be the angle of deviation if angle of incidence is 30 degree?
A + D = 30 + 30
This shows that deviation of the angle from incidence is
zero
.
What is the angle of reflection if the angle of incidence is 30?
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
. As the angle of incidence and the angle of reflection are equal, both angles equal 60 degrees.
What is the angle of reflection if the angle of incidence is?
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
.
What is the angle of reflection if the angle of incidence is 35?
An incident ray makes an angle of 35° with the surface of a plane mirror. What is the angle of reflection? Therefore, Angle of reflection =
55°
.
What is the angle of reflection if the angle of incidence is 45 degree?
Explanation: According to the first law of reflection of light, if the angle of incidence is 45 degree then the angle between reflected ray and the incident ray will be
90 degree
.
When angle of incidence is 40 what will be angle of reflection?
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.
Why should angle of incidence be between 30 and 60?
In the case of 30 and 60 degrees of angle of incidence,
the refracted ray is easily observable so that we can find the angle of refraction and emergence accurately
. Hence, these angles are preferred.
What will be the angle of deviation if angle of incidence is 40?
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
.
What is the angle of deviation when angle of incidence is 60?
The angle of deviation will be
60°
only. As refracted ray goes strainght so it will be 90°.
What is the angle of incidence of angle of reflection 50 degree?
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 angle of reflection when the angle of incidence is 90?
– 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.
How do you calculate the angle of reflection?
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 angle of reflection?
:
the angle between a reflected ray and the normal drawn at the point of incidence to a reflecting surface
.
What do you know about angle of incidence?
In optics, angle of incidence can be defined as
the angle between a ray incident on a surface and the line perpendicular to the surface at the point of incidence
(called as normal). … We all know that when a ray of light hits a polished surface like a mirror, it is reflected back.
What would be the angle of reflection if an incident ray makes an angle of 70 degree with the normal of the plane mirror?
= 90 – 60 =
30 degrees
. Since, angle of incidence = angle of reflection = 30 degrees. The incident ray will have an angle of reflection of 30 degrees (made with a surface normal to the mirror surface).
