Types of Light Waves - Optics and Vision Test Review

Question 1

Define the following word: invisible spectrum

Answer 1

The invisible spectrum is radiation that is invisible to the human eye and is a portion of the electromagnet spectrum.

Question 2

Define the following word: electromagnetic spectrum

Answer 2

The electromagnetic spectrum is visible light, as well as other waves, such as infrared radiation, ultraviolet radiation, radio waves, and x rays.

Question 3

Answer 3

Lists -
Light moves at a straight line
Light can be refracted and reflected
Light is a form of energy
Light is something that the human eye can detect

Question 4

Define the following word: Wavelengths

Answer 4

The distance between the top of one wave and the top of the next wave is called the wavelength.

Question 5

Define the following word: Frequency

Answer 5

Numbers of times a wave source or medium vibrates is a given unit of time.

Question 6

Define the following word: Amplitude

Answer 6

Height of the wave from its middle rest position to its highest point.

Question 7

Answer the question -
What kinds of wavelength does a high frequency? And what kind of pitch sound would it be?

Answer 7

This time of frequency has a close and short wavelengths, and its pitch sound would be “high”.

Question 8

Answer the question -
What kinds of wavelength does a low frequency? And what kind of pitch sound would it be?

Answer 8

This time of frequency has a farther apart wavelength, and its pitch sound would be “low”

Question 9

Answer the question -

Answer 9

Flies:
- hundreds of thousands of tiny lens
- able to see ultraviolet(UV) light
- sees in slow motion.

Sharks:
-sees clearly in water
- see no color what so ever

Snakes:
-at night sees heat signature/infrared

Rats:
-each eye moves independently
- sees in slow motion
- sees in blurrness
- can’t see the color red.
