Chapter 8 Waves & Electromagnetic Radiation

What describes visible light?

• Red light has a longer distance between wave crests than blue

• Blue light has a shorter distance between wave crests than red light

• Yellow light has a shorter distance between wave crests than green

• Blue light has a longer distance between wave crests than red

• Orange light has shorter distance between wave crests than violet

Which process names what happens when light is transmitted from air to water during the formation of a rainbow?

• absorption

• amplification

• reflection

• refraction

The highness or lowness of sound is the

• pitch

• volume

• intensity

• density

Glass breaks when a sound's pitch is at the same ___________ of the glass and has more ___________.

• loudness, pitch

• frequency, intensity

• density, intensity

• frequency, volume

What would allow you to read something that is flipped from right to left?

• a magnifying glass

• looking at it upside down

• starting from the end and going backwards

• holding a mirror up to it

How do filters work?

• Certain colors of light pass through, leaving everything else blank or invisible

• Only the color matching the plastic can pass through, leaving everything else shades of black.

• ONly the color matching the plastic can pass through, leaving everything else blank or invisible

• All colors except the one that matches the plastic can pass through, leaving that color black.

Place the colors in order from highest frequency to lowest frequency: red, yellow, blue, orange, violet, green

Explain how you hear an echo.

• The sound is loud.

• The sound waves travel in a vacuum.

• The sound waves reflected off the canyon walls.

• The sound wave bend as they travelled into the canyon.

How would you describe longitudinal sound waves?

• Sound travel through a material to transfer energy.

• Sound must travel through a vacuum to transfer energy.

• Rarefaction and compression are properties of longitudinal waves

• Crests and troughs ar properties of longitudinal waves.

What is the definition of frequency?

• the distance a wave travels before repeating

• the distance a wave travels in a certain amount of time

• the number of waves that pass a given point in a certain amount of time

• half the vertical distance from the trough to the crest of a wave.
