Size of image is independent of the incidence angle. Thus, for a fixed incident ray, the reflection angle is twice the angle through which the mirror has rotated. When a plane mirror
What will be the angle through which reflected ray?
The normal line divides the angle between the incident ray and the reflected ray into two
equal angles
. The angle between the incident ray and the normal is known as the angle of incidence. The angle between the reflected ray and the normal is known as the angle of reflection.
When a plane mirror is rotated through an angle the reflected ray turns through?
[SOLVED] When a plane mirror is rotated through an angle theta , then the reflected ray turns through the angle 2theta , then
the size of image
.
When a mirror is rotated by 20 degree by what angle reflected ray rotate?
On rotating a mirror through an angle of 20°, the reflected ray is found to get deviated through an angle Ans :
40°
.
When a plane mirror is fixed and the incident ray is rotated by 10 clockwise the reflected ray will rotate by?
Answer Submitted
(ii) When the mirror is rotated clockwise, angle of incidence increases by 10 and thus angle of reflection will move clockwise(+10). Hence, after combining both results (-10+10 = 0), reflected ray will rotate by
ZERO degrees
.
How many images are formed when two plane mirror is kept at an angle of 30?
∴ There will be
11 images
formed when two mirrors are placed at an angle of 30°.
What will be the angle through which reflected ray will rotate the incident ray is kept fixed and mirror is rotated through an angle theta?
Complete answer:
Thus, for a fixed incident ray, the reflection angle is
twice the angle through which the mirror
has rotated. When a plane mirror is rotated at an angle θ, the reflected ray rotates through the angle 2θ.
What should be the angle between two plane mirrors?
what should be the angle between two plane mirrors so that whatever be the angle of incidence the incident ray and the reflected ray from the two mirror be parallel to each other. The angle of inclination between two mirrors should be
90 degrees
.
Are is incident at an angle 38 degree on a mirror the angle between normal and reflected ray is?
According to the question, the ray is incident at an angle of 38∘ with the mirror. By the laws of
reflection
, we know that the angle of incidence is equal to the angle of reflection. But both the angle of incidence and the angle of reflection are measured with the normal to the mirror at the point of incidence.
At what angle from horizontal Must we keep the mirror in order to get a vertical reflected ray?
The angle of incidence is equal to equal to the angle of reflection, i.e. Hence, the answer is
60∘
.
Which mirror has maximum field of view?
Thus,
convex mirrors
have the largest field of view.
What is the relation between angle of incidence and angle of reflection?
The law of reflection states that
the angle of incidence is equal to the angle of reflection
. The angle of incidence is the angle between the incident ray and the normal. The angle of reflection is the angle between the reflected ray and the normal at the point where the reflection occurs.
Is a vector necessarily changed if it is rotated through an angle?
Yes. A vector is defined by its magnitude and direction, so a vector can be changed by changing its magnitude and direction. If we rotate it through an angle,
its direction changes
and we can say that the vector has changed.
When the incident light ray is fixed if mirror rotates through an angle theta?
For a fixed incident light ray, if the mirror be rotated through and angle theta (about an axis which lies in the plane of mirror and perpendicular to the plane of incidence), show that the
reflected ray turns
through an angle 2theta in same sense.
When an incident light ray is parallel to the mirror at what angle is it reflected?
A mirror illuminated by many parallel rays reflects them in only one direction, since its surface is very smooth. Only the observer at a particular angle will see the reflected light. The law of reflection is very simple: The angle of reflection
equals the angle of incidence
.
What is the rotation of light in plane mirror?
Thus the angle of deviation of a ray by a plane mirror is equal to the twice of the glancing angle. The law of rotation of light states that “when a mirror rotates
through an angle Ï ́, then the reflected rotates through angle 2Ï ́
.”
