What happen when a ray of light falls normally on a reflecting surface?

As light rays pass from one medium into another, they bend (or "refract"). This can be easily seen by trying to poke at something under water from above the surface (for example, aim a drinking straw at a target in a glass of water). This refraction is a consequence of the change in direction due to the wave-qualities of light, as the speed of the light is affected by the change of medium.

∙ 12y agoif ray of light falls normally ,it is reflected back along the same path
Wiki User
∙ 12y agoIn general, its speed changes. Also, its direction changes
if it isn't initially perpendicular to the boundary.

The portion of a light ray that falls on a surface is?
The portion of a light ray that falls on a surface is incident ray.
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.
How does air above a cooled surface move?
Air above a cold or cooled surface contracts and falls.
Why does not white light when falls on objects makes them appear as black or white?
Many objects do appear black or white when light falls on them. If they are black, it means that the object is absorbing all wavelengths of visible light and not reflecting any. If they are white, it means that they are reflecting all wavelengths of visible light and not absorbing any. The color of an object is due to the wavelengths of light that it reflects.
What will happen when white light falls into an object?
It will be illuminated. Whatever else may happen depends on the substance the object is made from.
Difference between refracting and reflecting?
Reflection is bouncing back of light after falling on a polished surface while refraction is bending of light when it falls on a surface
What happen when a ray of light falls perpendicular to the surface of mirror?
it reflects
What is the difference between an incident ray and a reflected ray?
The ray which hits or falls on a object or a material initially is known as INCIDENT RAY. The ray which gets reflected after hitting the object is known as REFLECTED RAY.

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

easy its a meteorite
When reflecting light?
light is reflected when it falls on some object. every object has the ability to reflect light.
Has Niagra Falls ever froze?
Part of the Falls will freeze in the winter, not where the actual falls are, but the surrounding parts where some of the water hits, then at night the coloured lights are reflecting off the ice, it is quite beautiful to see.
Is niagara falls in Canada is it surface water or underground water?
The horse shoe falls is in canada , The bridal veil falls and the american falls arre in america, It is surface water because it comes from Lake Erie
Falls for foul drainage?
For 100mm pipes, the type normally used for residential drainage, the minimum acceptable falls are 1:40 for Foul Water and 1:100 for Surface Water. Larger diameter pipes may have gentler gradients in certain circumstances.
