# What happens when a light ray hits a smooth surface?

## What happens when a light ray hits a smooth surface?

In reflection, a light ray strikes a smooth surface, such as a mirror, and bounces off. A reflected ray always comes off the surface of a material at an angle equal to the angle at which the incoming ray hit the surface. In physics, you’ll hear this called the law of reflection.

### What kind of reflection takes place on a smooth surface?

Light reflects from a smooth surface at the same angle as it hits the surface. For a smooth surface, reflected light rays travel in the same direction. This is called specular reflection

Why do light rays reflect at different angles?

Of course, we live in an imperfect world and not all surfaces are smooth. When light strikes a rough surface, incoming light rays reflect at all sorts of angles because the surface is uneven. This scattering occurs in many of the objects we encounter every day.

How are rays and wave fronts related to the law of reflection?

In particular, we’ll use rays and wave fronts to analyze how light interacts with mirrors and lenses. The law of reflection Objects can be seen by the light they emit, or, more often, by the light they reflect. Reflected light obeys the law of reflection, that the angle of reflection equals the angle of incidence.

Light reflects from a smooth surface at the same angle as it hits the surface. For a smooth surface, reflected light rays travel in the same direction. This is called specular reflection.

## What is the behavior of light that light bounces?

Reflection
Reflection. Reflection is when incident light (incoming light) hits an object and bounces off.

### How does light bounce smooth surfaces?

Light reflecting off a smooth surface, where all of the light is reflected in the same direction, is called specular reflection. The normal at different spots along the rough surface points in different directions, which causes the reflected light to go in different directions. This is called diffuse reflection.

How does a ray of light behave when it hits a surface?

Rays of light usually travel in straight lines until they hit something. When a light ray passes from air into water a similar thing occurs: the light ray is bent as it strikes the surface of the water. This ‘bending of a ray of light’ when it passes from one substance into another substance is called refraction.

What is the Behaviour of light?

When light moves from one medium (like air) to another medium (like water) it will change directions. This is a “wave-like” behavior and is called refraction. In this way light behaves like other waves such as sound waves. The speed of the light wave also changes when it moves from medium to medium.

## How does a light ray bounce off a surface?

Let’s take a second to discuss each one. In reflection, a light ray strikes a smooth surface, such as a mirror, and bounces off. A reflected ray always comes off the surface of a material at an angle equal to the angle at which the incoming ray hit the surface. In physics, you’ll hear this called the law of reflection.

### When does light bounce off an object it is called?

Reflection of light. Reflection is when light bounces off an object. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. This is called specular reflection. Light reflects from a smooth surface at the same angle as it hits the surface.

What do you call the reflection of light on a smooth surface?

This is called specular reflection. Light reflects from a smooth surface at the same angle as it hits the surface. For a smooth surface, reflected light rays travel in the same direction.

How does the law of reflection apply to light?

How Light Works. Let’s take a second to discuss each one. In reflection, a light ray strikes a smooth surface, such as a mirror, and bounces off. A reflected ray always comes off the surface of a material at an angle equal to the angle at which the incoming ray hit the surface. In physics, you’ll hear this called the law of reflection.
