Q:

Can light bend?

A:

Yes, light can bend through diffraction and refraction. Diffraction is when light bends around a corner or a small opening and fills the larger space beyond it. Refraction is the bending of light when it transitions through different mediums, such as light seen in the air and entering into water.

Light travels at different speeds through different mediums, which causes refraction. When light passes from one medium to another, it slows down or speeds up. This causes the light to bend. Refraction is responsible for image formation in eyes and in cameras. Rainbows are also a result of refraction, where blue light is refracted more than red light.

  • Q:

    What are examples of diffraction?

    A:

    A common example of diffraction of light is looking at an object that is partially immersed in water, where the object appears to be in a different place. Sound diffraction is usually not visible, but it is audible through walls or other solid objects.

  • Q:

    What does diffraction grating do?

    A:

    Reference.com states that a diffraction grating is an optical component that can split light into separate beams traveling in different directions. The space between each beam depends both on the light wavelength and the spacing of the grating.

    How do we see light?

    A:

    The human eye sees light with the pupil and the retina. Located inside the retina are two types of special cells called photoreceptor cells. There are two varieties of photoreceptor cells known as cones and rods.
