Light Energy

PRISM

A solid glass or plastic object that light can pass through that refracts light and splits it into the colors of the rainbow.

Transparent

All the Light will pass through See Through EX. Glass, Plastic Wrap, Water, Window Glass, Sprite

Telescope

An instrument that uses lenses and sometimes mirrors to make distant object appear larger by gathering and focusing light

In which body of water can you see your reflected image better, a pond or an ocean? Why?

Because when the sunlight reflects down it bounce off and we can see us staring down at the water.

Opaque You cant see through it

Cardboard: Transparent / Translucent / opaque? Describe

Laser

Device that makes a strong, narrow beam of light

In what ways do different material refract light?

Different kinds of lens refract light. the shapes of lenses cause light to refract in Different ways.Convex Lens - Thicker in the middle bends light rays that pass through it to a focal point (EX. Magnifying Glass) Concave lens - thinner in the middle spreads light rays apart as they pass through it. EX. Flashlight Prism - Refracts different wave lengths at different angles, Producing a spectrum of colors. DRAW EXAMPLES of lens

Transparent It is clear and you can see through it.

Drinking Glass Transparent / Translucent / Opaque? Describe

What happens to light when it passes through a transparent material?

Light waves refactor bend as they pass through transparent materials, Refraction - Light bends as it travels from one transparent material into another.

Opaque

NO light passes through EX. Mirror, Brick Wall, Wood, White board

Natural Light

Natural light or Artificial light

Lens

Piece of clear material, such as glass or plastic that bends light rays as they pass through, can either focus or spread light rays

Transparent It is clear. and light goes through it when you shine light on it

Plastic Wrap : Transparent / Translucent / Opaque? Describe

What is the difference between light reflection and refraction?

Reflection - Bouncing of light off a surfaces.Refraction - Bending of light as they pass through is medium to another.

Rough Reflection

Rough Reflection

Is this a Rough or Smooth reflection?

Smooth

Mirror

Smooth Surface that reflects an image of what is in front of it

Translucent

Some light Passes through MT, Dew/ Lamp shade, Paper Tissue

Light spectrum

The small part of the electromagnetic spectrum that the human eye can see including the colors red, orange, yellow, green, blue, violet

Which surface reflection the deer's image? Why?

The surface of water is very smooth and shiny. The light rays that strike it is reflected evenly. So, it reflects a mirror image.

Translucent it is not clear. But you can see through it.

Tissue Paper : Transparent / Translucent / Opaque?Describe

What happens when light hits a surface?

When light hits a smooth surface it bounces evenly.when light hits a rough surface it bounces unevenly and scatters

Compare and Contrast how smooth and rough surfaces reflect light.

When light waves strikes a rough surface, they are reflected unevenly, When light waves strikes a smooth surface they are reflected even

Translucent you cant see through it but when you put a light on it you can see through.

Your Hand Transparent / Translucent / Opaque?Describe

Concave Lens

a lens that curves inward Spreads light rays apart as they pass through it *Helps people see faraway EX. Flashlight, Telescope

Kaleidoscope

a tube with mirrors and colorful beads or glass inside of it, when the tube is held to the eye and rotated, patterns can be seen as the objects reflect off the mirrors

Convex lens

its a lens that curve outward. it bends lite rays that pass through it to focal point. *Helps people see close up Ex. Magnifying glass

Refraction

the bending of light rays, bending light means that it changes direction and/or speed

Reflection

the bouncing off of light rays from the surface of an object such as a mirror or other shiny surface

Magnify

to cause to appear larger

Artificial

"Natural or Artificial Light"

Absorb

"Take in"Heat is sometimes a result All the colors are absorbed and red is reflected
