Front 12

to bend light or sound waves as they pass through different mediums

Back 12

refract

Front 13

to bounce energy off an object

Back 13

reflect

Front 14

a lens that focuses light

Back 14

Front 15

a lens that causes light to spread out

Back 15

Front 16

______ & ______ are two kinds of kinetic energy

Back 16

Light & Sound

Front 17

True or False

Light interacts with matter by passing through it, bouncing off it, or staying inside it

Back 17

True

Front 18

True or False

Light and sound travel as waves

Back 18

True

Front 19

True or False

Light is a type of electromagnetic radiation that does not require a medium

Back 19

True

Front 20

True or False

Sound is not electromagnetic radiation and does require a medium to travel through.

Back 20

True

Front 21

True or False

Light and sound interact with matter in specific ways.

Back 21

True

Front 22

True or False

Light and sound can be used for communication

Back 22

True

Front 23

True or False

Waves with high amplitudes transfer more energy than waves with low amplitude

Back 23

True

Front 24

High pitches are made by _______

Back 24

High-frequency sound waves

Front 25

Low pitches are made by _______

Back 25

Low-frequency sound waves

Front 26

What are some differences between light and sound?

Back 26

1. sound waves need a medium (way to move) but light does not.

2. they have different wavelengths and frequencies

3. light travels much faster than sound

4. light travels as transverse wave; sound travels as a longitudinal wave

5. light comes from sources such as the sun, stars or fire; sound is produced whenever an object causes the air around it to vibrate

Front 27

What part of the electromagnetic spectrum can the human eye see?

Back 27

white light

Front 28

When white light passes through a prism, it gets separated into seven colors known as the ___________

Back 28

visible spectrum

Front 29

Where else can the visible spectrum be seen?

Back 29

in a rainbow

What objects allow only some light to pass through?

Back 31

translucent

Front 32

What objects do not allow any light to pass through?

Back 32

opaque

Front 33

What object refracts or bends light?

Back 33

water

Front 34

True or False

Darker objects absorb more light than lighter objects.

Back 34

True

Front 35

True or False
