## What is the main difference between refraction and diffraction Brainpop?

Refraction involves the bending of light; Diffraction involves the bending and spreading of light-usually around objects. Refraction involves changes to the density of light; Diffraction involves changes to the speed of light.

## What kind of stuff can be refracted?

Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another. This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms and rainbows. Even our eyes depend upon this bending of light.

## Why does white light from the sun form a colorful rainbow when it passes through water droplets in the atmosphere?

Rainbows appear in seven colors because water droplets break sunlight into the seven colors of the spectrum. You get the same result when sunlight passes through a prism. The rainbow effect occurs because the light is then reflected inside the droplet and finally refracted out again into the air.

## What is diffraction and refraction?

Refraction is the change in direction of waves that occurs when waves travel from one medium to another. Diffraction is the bending of waves around obstacles and openings. The amount of diffraction increases with increasing wavelength.

## Which is the best example of diffraction?

The effects of diffraction are often seen in everyday life. The most striking examples of diffraction are those that involve light; for example, the closely spaced tracks on a CD or DVD act as a diffraction grating to form the familiar rainbow pattern seen when looking at a disc.

## Which of the following is the best example of refraction?

One of the best examples of this is when a pencil is put in a half-filled glass of water. Notice how the pencil above the water looks normal, but under the water, it looks bent and slightly larger. This is because of refraction.

## Why is rainbow arched?

The rainbow is curved as it reflects the round shape of the sun. Rainbows are circular because raindrops are spherical. When light from the Sun enters a raindrop it is largely reflected back inside a cone with a half-angle of 42 degrees.

## What is the difference between scattering and diffraction?

For any type of wave, one way to define diffraction is the spreading of waves, i.e., no change in the average propagation direction, while scattering is the deflection of waves with a clear change of propagation direction. The intensity distribution of this wave yields what is commonly called the diffraction pattern.
