What is the Dual Nature of Light

Light modeled as a particle and a wave. 1 PT Light modeled as a particle and a wave.

What is a small packet of light energy

2 PT A photon.

It’s what light carries and transfers.

3 PT Energy

Evidence for the wave model of light.

Reflection, refraction, diffraction and interference. 4 PT Reflection, refraction, diffraction and interference.

Evidence for the particle model of light.

Photons and the photoelectric effect. 5 PT Photons and 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 lowest to highest energy.

5 PT Radio waves, microwaves, infrared light, visible light, ultra-violet light, x-rays and gamma rays.

The angle of incidence equals the angle of reflection

1 PT Law of reflection

It’s what happens to light as it passes from a less dense to more dense medium

It refracts. (slows down and bends toward the normal line) 2 PT It refracts. (slows down and bends toward the normal line)

The coming together of light rays

3 PT convergence

The separation of white light into its component colors due to refraction or diffraction.

4 PT dispersion

The shape of the cornea and lens in the eye

5 PT convex

What is color?

A range of frequencies representing visible light 1 PT A range of frequencies representing visible light

The primary colors of light

2 PT Red, green and blue

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

Magenta, cyan and yellow 3 PT Magenta, cyan and yellow

It’s the absence or absorption of all color

4 PT black

This color is bent the least as it passes through a prism

5 PT red

These structures, which occur in equal ratios on the retina, respond to different frequencies of visible light.

Red, green and blue cone cells 1 PT Red, green and blue cone cells

A material that only allows one plane of light to pass through.

2 PT polarizer

Three boundary interactions that occur in a raindrop, which lead to the forming of a rainbow

3 PT Refraction (dispersion), total internal reflection and refraction (dispersion)

Fiber optics works because of this phenomenon.

Total internal reflection 4 PT Total internal reflection

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

5 PT Light intensity
