Refraction of Light

Science

Not quite remember

I easily remember

Refraction

The change in direction of a wave passing from one medium to another caused by its change in speed

Refraction of light

When light travels through two different mediums, the direction of movement of the light will change

Medium

Something that allows light to pass through like air and water

The speed of light in a different medium

The speed of light will be different when passes through different mediums

Example of devices that uses the principle of light refraction

Magnifying glass, telescope and microscope

The reason why fish appear closer to the water surface

Light refraction causes light to form the image of the fish closer to the surface than the actual location of the fish

The reason why insects appear bigger on the magnifying glass

Light refraction causes the image of the fish to become bigger on the lens of the magnifying glass

Incident angle

Angle of incidence

Refraction angle

Angle of refraction

The ray of light after travelling into a denser medium

The light ray will be refracted closer to the normal line
