What is angle of incident if the reflected ray is 90 degree to incident ray?
The angle of incident is 45 degrees. The incident and reflected ray have the same magnitude and if the sum of the magnitudes is 90 degrees the incident is 45 degrees.
What will be the angle of reflection if a ray of light is incident towards a plane mirror at an angle of 45 degrees with the mirror surface?
The law of reflection: When a ray of light reflects off a mirror, the angle of the incidence ray is equal to the angle of the reflection ray. Therefore, an incidence ray of 45 degrees will have a reflection ray of 45 degrees. As both rays are equal, either side of the normal line, then adding both angles equals 45 + 45 = 90 degrees. The normal line is a line perpendicular to the surface of the mirror.
What is the angle of incidence of a ray if the reflected ray is at an angle of 90 to the incident ray?
The angle between the incident ray and reflected ray is known as angle of deviation due to reflection. This will always be equal to 2i. Here i is the angle of incidence. So if 2i = 90 then i = 90/2 = 45 So the angle of incidence has to be 45 deg
What happens to the angle of reflected light rays as the angle of incident light rays becomes steeper?
The angle of incidence equals the angle of reflection. Therefore, if your angle of incidence is 15 degrees, your angle of reflection equals that also. If it is 45 degrees, your angle of reflection is also 45 degrees, and so on.
Is a 45 degree angle an oblique angle?
An oblique angle is any angle not 90 degrees or a multiple of 90 degrees. So 45 degrees is an oblique angle. A 45 degree angle is also an acute angle (anything less than 90 degrees).
What is angle of incident if the reflected ray is 90 degree to incident ray?
The angle of incident is 45 degrees. The incident and reflected ray have the same magnitude and if the sum of the magnitudes is 90 degrees the incident is 45 degrees.
What is angle of incidence of a ray if the reflected ray is at an angle of 90 degree of the incident ray Verify the answer with diagram?
Call the angle from the incident ray to the normal X. The angle of the reflected ray to the normal also has to be X because the incidence angle and the reflected angle are equal by law of reflection. Since the angle between the reflected and incident ray is 90 degrees: 2*X = 90 So, X = 45 degrees.
What will be the angle of reflection if a ray of light is incident towards a plane mirror at an angle of 45 degrees with the mirror surface?
The law of reflection: When a ray of light reflects off a mirror, the angle of the incidence ray is equal to the angle of the reflection ray. Therefore, an incidence ray of 45 degrees will have a reflection ray of 45 degrees. As both rays are equal, either side of the normal line, then adding both angles equals 45 + 45 = 90 degrees.

What happens to the angle of reflected light rays as the angle of incident light rays becomes steeper?
The angle of incidence equals the angle of reflection. Therefore, if your angle of incidence is 15 degrees, your angle of reflection equals that also. If it is 45 degrees, your angle of reflection is also 45 degrees, and so on.
Is 45 degrees a reflex angle?
no a reflex angle is 145
Is a 45 degree angle an oblique angle?
An oblique angle is any angle not 90 degrees or a multiple of 90 degrees. So 45 degrees is an oblique angle. A 45 degree angle is also an acute angle (anything less than 90 degrees).
What happens when a light ray is shone at a mirror?
It is reflected. Depending on the shape of the mirror, this can be at a variety of angles. Assuming the question refers to a flat mirror that is hung on a wall; a plane (flat) mirror has an imaginary straight line at a right-angle to it, called the normal. A ray of light hits the mirror at an angle to the normal, but is reflected at the same angle that it hits the mirror in the opposite direction. So if a ray hits the mirror at 45 degrees from the normal, it will be reflected at 45 degrees from the normal in the opposite direction.
What is a measure of each angle formed by bisecting a right angle?
45 degrees. 45 degrees
What is the compliment and supplement of 45?
compliment angle = 45 degrees and supplement angle = 135 degrees
What is the measure in degrees of the third angle of a right triangle with an angle of 45 degrees?
Also 45
According to the law of reflection if the angle of incidence is 45 degrees what is the angle of reflection?
If the angle of incidence is 45 degrees, then the angle of reflection will also be 45 degrees. This is because the angle of incidence is always equal to the angle of reflection according to the law of reflection.
