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.
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.
An activity to show that the incident ray the reflected ray and the normal at the point of icident ray lie in the same plane?
Place a plane mirror on the table. Take a paper sheet and make a small hole in its centre. Make sure that the light in the room is not bright. Hold the sheet normal to the table. Take another sheet and place it on the table in contact with the vertical mirror. Draw a normal line on the second sheet from the mirror. Now, light a torch on the mirror through the small hole such that the ray of light falls on the normal at the bottom of the mirror. When the ray from this hole is incident on the mirror, it gets reflected in a certain direction. You can easily observe the incident ray, reflected ray and the normal to the mirror at the point of incidence on the sheet placed on the table. This shows that the incident ray, the reflected ray, and the normal to the surface at the point of incidence all lie in the same plane.
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.
How can a plane mirror ray diagram be used to illustrate the reflection of light?
A plane mirror ray diagram can be used to show how light reflects off a mirror. It helps visualize the angle of incidence being equal to the angle of reflection, and how the reflected rays form an image.
A light ray hitting a mirror at an angle is reflected off at angle?
The angle between the incident ray and the mirror is equal to the angle between the reflected ray and the mirror.
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.
Why does a ray falling on a plane mirror retrace its path?
The ray (torch beam) is reflected off the shiny surface of the mirror at an angle. It doesn't retrace its path unless the ray hits the mirror at 90 degrees. It is known as the angle of reflection. A bouncing ball shows the same effect.
What is the angle between the incident and reflected rays when a ray of light is incident normally on a plane mirror?
When a ray of light is incident normally on a plane mirror, the angle between the incident ray and the reflected ray is 0 degrees. This means that the reflected ray will travel back along the same path as the incident ray, creating a symmetry in the reflection process.
What is the reflected ray when it is reflecting on another mirror?
When a ray of light reflects off a mirror and then onto another mirror, the direction of the reflected ray is determined by the angle of incidence relative to the surface of the second mirror. The law of reflection states that the angle of incidence equals the angle of reflection, so the reflected ray will bounce off the second mirror at an equal but opposite angle to the incident ray.
Why does image formed in a plane mirror is always virtual?
the ray that passes from the object, when gets reflected from the plane mirror,the imaginary ray that passes from the mirror meets at a point behind mirror but the original do not meet actually.so the image formed by plane mirror is virtual.
What is the plane at which the incidence ray the reflected ray and the normal lie?
The plane at which the incident ray, the reflected ray, and the normal lie is known as the plane of reflection. This plane is perpendicular to the surface of the reflecting object and contains all three of these elements.
