What is the angle of incidence when a ray falls normally on a mirror?
0 degrees
What is the angle of incidence when a ray of light falls on spherical mirror from its centre of curvature?
That ray of light is just a radius of the sphere. It's perpendicular to the sphere everywhere, so the angle of incidence is zero ... the ray of light arrives along the normal to the mirror at any point.
What happen when a ray of light falls perpendicular to the surface of mirror?
it reflects
What kind of angle is 109?
An angle measuring 109 degrees is classified as an obtuse angle. In geometry, an obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees. In this case, the angle of 109 degrees falls within this range, making it an obtuse angle.
What is a 49 degree angle?
A 49-degree angle is an acute angle that measures 49 degrees between two intersecting lines. It is less than 90 degrees, making it acute. In geometric terms, it falls between a 0-degree angle (a straight line) and a 90-degree angle (a right angle).
What is a angle of reflection when ray of light falls normally on a plan mirror?
The angle of reflection is equal to the angle of incidence when a ray of light falls normally on a plane mirror. This means that the light ray will be reflected back at the same angle at which it struck the mirror.
What degre3e is the angle of reflection if a ray falls normally on a plane mirror?
0o
What happens to a path of a light beam when it falls on a mirror?
When a light beam falls on a mirror, it gets reflected following the law of reflection. The angle of incidence (the angle at which the light beam strikes the mirror) is equal to the angle of reflection (the angle at which the light beam bounces off the mirror). This process allows us to see our reflection in mirrors.
Why does a ray falling normally on a plane mirror retrace its path?
When a ray falls normally on a plane mirror, it is reflected back along the same path due to the law of reflection, which states that the angle of incidence is equal to the angle of reflection. Since the incident angle is zero degrees, the reflected ray also follows the same path.
Which phenomenon occurs when light falls on a smooth mirror?
When light falls on a smooth mirror, it undergoes a process called specular reflection, where the light is reflected at the same angle as it hits the mirror's surface. This results in a clear and sharp reflection of objects in the mirror.
What is the angle of incidence when a ray falls normally on a mirror?
0 degrees
What happens if light falls on the mirror?
When light falls on a mirror, it is reflected back towards the source. This reflection occurs based on the law of reflection, where the angle of incidence is equal to the angle of reflection. Mirrors are designed to reflect light, allowing us to see clear and sharp images of objects.
The angle of incedence is equal to the angle of reflection?
This is the second law of reflection phenomenon. So if a ray falls normally on the reflecting mirror then the angle of incidence will be 0. So as the angle of reflection also is to be 0, the ray just retraces its path. That is it is coming back in the same straight line.
What happens a ray of light falls on a plane mirror?
When a ray of light falls on a plane mirror, it undergoes reflection. The angle at which the light ray strikes the mirror is equal to the angle at which it reflects off the mirror. This allows us to see a reflected image of the object from which the light ray originates.
What happens when light falls on a polished surface?
When light falls on a polished surface, it gets reflected off the surface at an equal and opposite angle to the angle at which it hit the surface. This reflection creates a mirror image of the original light source.
Why does a ray falling on a plane mirror retrace its path?
When a ray of light falls on a plane mirror, it reflects at the same angle as the angle of incidence. This causes the reflected ray to retrace its path back towards the light source. This is known as the law of reflection.
How many reflected rays can there be for a single incident ray falling on a plane mirror?
Substitute "photon" for "ray" and it's one. One photon falling on a plane mirror will come back off of the reflective surface if that reflective surface does not absorb it. (In a perfect plane mirror, every photon that falls on the surface will be reflected.) A photon does not "create" a second photon in a reflection event.
