J E O P A R D Y The Energy of Light

Reflect or Refract Mirror, Mirror Light Matters Light Travel How Illuminating!

A good reflector of light has these two characteristics.

What are smooth and shiny?

The angle of reflected light leaving an object

What is the angle of reflection?

The angle of light going in to an object

What is the angle of incidence?

When light bends by traveling from one medium through another, like from air through water

What is the refraction of light?

This is an instrument that has reflections of reflections often made prettier using colored objects like tiny pebbles.

What is a kaleidoscope?

These two types of mirrors don’t just reflect light, they bend it.

What are convex and concave mirrors?

A store’s mirror that allows the clerk to see all around the store, for example

What is a convex mirror?

A concave mirror like a make-up mirror allows you to do this.

What is magnify what you are looking at in the mirror?

A plane mirror creates this between an image and its reflection.

What is a line of symmetry, or axis of symmetry?

What the zero line that is perpendicular to the mirror is called to form a good starting point.

What is the normal?

If an object doesn’t allow light to pass through it, it is this.

What is opaque?

A window or a drinking glass allow light to pass completely through, and we can see clearly through them. They are this.

What is transparent?

Wax paper or frosted glass allow scattered light to go through, but we can’t see clearly through them. They are this.

What is translucent?

This is what happens to light when it can’t go through an object, or be reflected.

What is absorbed?

This changes as light passes through matter of different densities, like from water through air.

What is either the light’s speed or the angle of the light’s path ?

Light travels in this kind of path.

What is in a straight line?

Hey Sunshine, this is a thin beam of light.

What is a ray?

The reflection from a plane mirror creates this between the actual image and its reflection.

What is symmetry?

Two ways light can be bent, or made to change its path.

What are reflection and refraction?

Light travels at this speed.

What is about 186,000 miles per second?

This is created on the other side of an opaque object when light shines on it.

What is a shadow?

ROY G. BIV stands for this.

What is red, orange, yellow, green, blue, indigo, and violet?

The sun, a candle, and a light bulb are examples of light sources. They are this term.

What is luminous?

A light year measures this.

What is the distance light travels in a year?

A glowworm can produce its own light. This is an example of blank.

What is bioluminescence?
