Waves Quiz

What are the two main types of waves?

• Radio waves and microwaves

• Longitudinal waves and transverse waves

• Sound waves and light waves

• The two main types of waves are mechanical waves and electromagnetic waves.

What is the definition of wavelength?

• The speed of a wave

• The amplitude of a wave

• The number of waves passing a point per second

• The distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.

Which type of wave requires a medium to travel through?

• Sound waves

• Transverse waves

• Electromagnetic waves

• Mechanical waves

What is the speed of sound in air?

• The speed of sound in dry air at 20 °C (68 °F) is approximately 343 meters per second (1,125 ft/s).

• The speed of sound in air is 700 meters per second

• The speed of sound in air is 500 meters per second

• The speed of sound in air is 100 meters per second

What is the difference between transverse and longitudinal waves?

• Transverse waves move perpendicular to the direction of the wave, while longitudinal waves move parallel to the direction of the wave.

• Transverse waves move parallel to the direction of the wave, while longitudinal waves move perpendicular to the direction of the wave.

• Transverse waves move in a zigzag pattern, while longitudinal waves move in a wave pattern.

• Transverse waves move in a circular motion, while longitudinal waves move in a straight line.

What is the frequency of a wave?

• The frequency of a wave is measured in meters (m)

• The frequency of a wave is measured in hertz (Hz).

• The frequency of a wave is measured in kilograms (kg)

• The frequency of a wave is measured in seconds (s)

What is the law of reflection?

• The law of reflection states that the angle of incidence is less than the angle of reflection.

• The law of reflection states that the angle of incidence is greater than the angle of reflection.

• The law of reflection states that the angle of incidence is unrelated to the angle of reflection.

• The law of reflection states that the angle of incidence is equal to the angle of reflection.

What is the color of light with the longest wavelength?

• Blue

• Yellow

• Green

• Red

What is the relationship between frequency and pitch in sound waves?

• Higher frequency corresponds to lower pitch, and lower frequency corresponds to higher pitch

• The relationship between frequency and pitch in sound waves is that higher frequency corresponds to higher pitch, and lower frequency corresponds to lower pitch.

• Frequency has no effect on pitch

• Higher frequency corresponds to higher pitch, and lower frequency corresponds to no pitch

What is refraction?

• Refraction is the speed of light in a vacuum

• Refraction is the reflection of light off a surface

• Refraction is the absorption of light by a material

• Refraction is the change in direction of a wave, such as light or sound, as it passes from one medium to another.
