5th Grade Light STAAR Review

Refraction is the bending of light as it passes from one medium to another, causing objects to appear shifted from their actual position.

Lenses refract light because they are made of transparent materials that change the speed of light as it passes through them.

The main function of a microscope is to magnify small objects so that they can be seen in greater detail.

Light travels in straight lines until it encounters a medium or an obstacle.

When light hits a reflective surface, it bounces back, a process known as reflection.

Transparent materials allow light to pass through completely, translucent materials allow some light to pass but scatter it, and opaque materials do not allow any light to pass through.

The objective lens in a telescope refracts light to gather and focus it, allowing distant objects to appear closer.

A fish appears closer to the surface due to the refraction of light as it passes from water to air, bending the light rays.

Reflection is the bouncing back of light when it hits a surface, allowing us to see images.

A medium is any substance through which light travels, such as air, water, or glass.
