The angle between the normal and the surface of anything is by definition always 90 degrees, regardless of whether it is a mirror, a piece of concrete, a wooden plank, etc.

If you point a laser beam at a 30 degree angle to a mirror will it reflect the same way?
This is essentially correct. A beam of light, when striking the plane of a mirror, will be reflected from that surface at the same angle as the incident beam.
How angle of incidence affect refractive index of a material?
The angle of refraction is the angle between the refracted ray and the normal (a perpindicular line to the tangent and the plane of the surface). A ray that enters at the normal angle leaves at the normal angle; there is no angle between the ray and the normal, so it is 0o.
Why light passes undeviated falling straight on a refracting medium?
If by "straight on" you mean at 90 degrees to the surface of the medium, that is because light is only deviated if it makes an angle with the normal, which is an imaginary line perpendicular to the surface of the medium. If no angle is made between the normal line and the light ray, then no refraction occurs and the light passes through in a straight line. For more information see the related link below.
What is a small angled surface formed between two surfaces?
acute angle.
What is the angle of incidence if the angle of reflection is 15 degrees?
If the ray is incident at right angles to the reflection surface, angle of Incidence will be 90 degrees and so will be the angle of reflection. In such a case, the incident ray, the normal and the reflected ray coincide.
What is plan mirror?
A plane mirror is a mirror with a planar reflective surface. For light rays striking a plane mirror, the angle of reflection equals the angle of incidence. The angle of incidence is the angle between the incident ray and the surface normal (an imaginary line perpendicular to the surface). Therefore the angle of reflection is the angle between the reflected ray and the normal and a collimated beam of light does not spread out after reflection from a plane mirror, except for diffraction effects.
What is the advantage of measuring the angle of reflection and angle incident on either side of the normal to the surface of the mirror?
We measure them on the either side of the mirror and not on the side of the normal to the surface of the mirror because, if the mirror or any reflecting surface is bent, then there will be a difference between the angle of incidence and angle reflection which can be avoided by measuring those angles on the either side of the mirror.
If the angle between the mirror and incident ray is 50 what will be the angle of incidence?
The angle of incidence is defined as the angle between the incoming light and the line that is normal to the surface at the point where the light 'hits' the surface. The reflectrion angle is the same as the incidence angle. If the angle between the incident ray and the mirror ray is 50, then the angle of incidence is half of this. That is, 25 degrees.
A ray of light is incident towards a plane mirror at an angle of 30-degrees with the mirror surfaceWhat will be the angle of reflection?
The angle of reflection is equal to the angle of incidence. It will be at 30o to the surface of the mirror (from the opposite edge) ^ This answer is not correct for SURFACE, but is correct for RELATIVE ^
What happen to light rays as it strikes a smooth and shiny surface liike mirror?
The light rays gets reflected in the same angle. Angle between normal and the incident ray is called angle of incident and angle between normal and reflected ray is called angle of relection. Normal is an imagenary perpendicular line on the reflecting surface. Angle of incidence is alway equal to angle of reflection.
The angle of incidence is the angle between the incident ray and the?
The angle of incidence is the angle between the incident ray and the normal (perpendicular) to the reflecting surface.
What happens when light hits a reflective surface?
It reflects with the angle of incidence (angle between the original ray of light and the normal (90 degrees to the mirror surface)) being the same as the angle of reflection (angle between the reflected ray of light and the normal). Some of the light energy is transferred into heat energy by the mirror, so the reflected beam is less bright than the original beam, but the difference is barely noticeable on a clean mirror.
What is the reflected angle for a light beam hitting a mirror?
The angle of the reflected ray with the normal line to the surface of the mirror is the same as the angle of incidence. Snell's law.
What will be the angle of reflection if a ray of light is incident towards a plane mirror at an angle of 30 degrees with the mirror surface?
If the ray hits the mirror at an angle of 30 degrees with the mirror surface, the complementary angle that the ray makes with the normal (perpendicular) to the mirror at the point of incidence is (90 - 30) = 60 degrees and since angle of incidence is equal to angle of reflection in a plane mirror, the angle of reflection is 60 degrees.
How do you find the angle of reflection off of a mirror?
The angle of reflection (θr) off a planar surface (eg. mirror) is equal to the angle of incidence (θi) on that surface. They are measured with respect to the normal, which is an imaginary line drawn perpendicular to the surface. Or, in simpler terms, the angle of reflection is the same as the angle of incidence.
The angle of incidence is the angle between what and the normal of the surface?
The angle of incidence it he angle at which the incident ray stikes the plane of the surface.
Differentiate Angle of reflection from angle of incidence?
The 'normal' direction is the direction perpendicular to a surface. Think of a stick with one end of it glued to a mirror. When a beam of light or a tennis ball hits the surface, the 'angle of incidence' is the angle between the normal and the direction the ball came from. The 'angle of reflection' is the angle between the normal and the direction the ball will take after the bounce. The angle of reflection will be equal to the angle of incidence. Knowing this, you can always place your bank shot exactly where you want it to go after the bounce.
