How does image formed by plane mirror?
A highly polishes plane surface which reflects light regularly is called a plane mirror. Image is formed as the light returns to the first medium when it just falls on the other surface of the second medium.
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 is the angle of reflection when a ray falls normally on a plane mirror?
90
What is the angle of incidence when a ray falls normally on a mirror?
0 degrees
Is it true that the thing that affects how fast it falls is the objects surface area?
Surface area is ONE thing that can affect how fast an object falls. Two forces determine how fast an object falls - the force of gravity and the opposing drag on the object from the medium it is falling through. In the case of an object falling in a vacuum, there is no drag so the object falls strictly according to the law of gravity. If an object is dropped through a fluid such as air or water, it can reach a terminal velocity where the force of gravity is exactly counterbalanced by the opposing drag on the object. In this case acceleration ceases - although motion does not. In other words, the object continues to fall, but it doesn't speed up. Drag force is a function of object velocity, viscosity of the fluid it is falling through, the surface area of the falling object, the surface roughness of the falling object, and the geometry of the falling object (spheres usually have less drag than cubes for example).
When does the shadow of an object short?
When the line from the light source to the surface on which the shadow falls is perpendicular to that surface.
When will your mirror shatter?
Answer: when you look into it with your hideous mug Answer: This may happen when the mirror falls on the floor.

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.
One difference between reflection and refraction of light waves is that?
reflection is when light its something like a mirror and refraction is light going through something solid that is not like a mirror when light falls on a surface and bounces back, it is reflection and when light is absorbed by the surface or passes through the surface but does not bounces back, it is refraction.
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.
Why is the ray passing through centre of curvature reflects along the same path?
Because a ray that passes through the center of curvature falls perpendicular to the surface (along a normal to the surface), hence it is reflected along the same path.
What happens if light falls on the mirror?
it reflects !
What will happen if water falls from a dam?
what will happen if falls from a dam
Why does a waxing gibbous happen?
The moon has reflective soil on its surface so when the earths shadow falls on it the suns rays don't reach the surface so making the moon shrink or grow
