Nature of Light

ElectromagneticSpectrum

Reflection and

Refraction Color

Light Effects

It’s what light carries and transfers.

1 PT

Energy.

It’s a small packet of light energy

2 PT

A photon.

What is the dual nature of light

3 PT

Light modeled as a wave and a particle

Evidence for the wave model of light.

4 PT

Reflection, refraction, diffraction and interference.

It’s the cause of the movement of electrons in a metal plate due to the interaction of photons with

specific frequencies.

5 PT

The photoelectric effect.

What is the form of the highest frequency of light?

1 PT

Gamma Rays

Radio waves has the lowest frequency and the ________

wavelength

2 PT

Longest

Which has the longer wavelength: infrared light or

ultraviolet light?

3 PT

Infrared light

Which has the higher energy: yellow light or green light?

4 PT

Green light

The seven forms of light, in order from highest to lowest photon

energy.

5 PTGamma rays, x-rays, ultraviolet light, visible light, infrared light,

microwaves and radio waves.

What is the angle of incidence equals the angle of reflection

1 PT

Law of reflection

The coming together of light rays

3 PT

convergence

It’s what happens to waves as they pass from one medium

through another

2 PT

Refraction.

The shape of the cornea and lens in the eye

5 PT

convex

What the different colors represent

2 PTDifferent frequencies or wavelengths of the

electromagnetic spectrum

It’s the absence or absorption of all color

4 PT

black

The primary colors of visible light

1 PT

Red, green and blue

Blue + red; blue + green; and green + red

3 PT

Magenta, cyan and yellow

The separation of white light into its component colors due to

refraction or diffraction.

4 PT

dispersion

These structures, which occur in equal ratios on the retina,

respond to different frequencies of visible light.

1 PT

Red, green and blue cone cells

This color moves fastest and is bent the least as it passes through

a prism

5 PT

red

A reflection that occurs when waves strike a rough surface.

2 PT

Diffuse reflection

This lens type is convergent.

4 PT

Convex lens

Vision problem related to the focal point appearing in front of

the retina

3 PT

Nearsightedness

It refers to the number of photons that pass through a given area,

increasing brightness

5 PT

Light intensity
