Waves

What impact does increasing the amplitude of a sound wave have on the volume of the sound?

• Increases it

• Decreases it

• No effect

What impact does increasing the amplitude of a sound wave have on the pitch of the sound?

• Increases it

• Decreases it

• No effect

What does increasing the frequency of a wave do to the wavelength of a wave

• Increases it

• decreases it

• No effect

When you change the frequency of light waves you impact the

• brightness of the light

• color of the light

• angle of the light

• reflection of the light

Why does a red apple look red?

• It absorbs the red light reflecting all other colors

• It absorbs all the other colors of light but reflect red

• Only red light hits apples

• It has been allowed to ripen longer

The same sound wave is sent through three different conditions (medium) air, water, and iron. Which one will it travel fastest through?

• Iron, because it is the most dense so the molecules can pass the energy on faster

• water, because it moves around the easiest

• air, because it is the least dense so their are less molecules for the energy to go through

When you turn down the volume on the music playing through your head phones what impact does that have on the energy of the sound waves

• The energy is decreased because the amplitude is lower

• The energy is decreased because the frequency is lower

• The energy is increased because the amplitude is lower

• The energy is increased because the frequency is lower

What two factors influence the amount of energy a wave has?

• The direction the wave is travelling

• The height of the source of the wave

• The amplitude of the wave

• The frequency of the wave

When you increase the amplitude of a sound wave you

• increase the volume of the sound

• decrease the volume of the sound

• increase the pitch of the sound

• decrease the pitch of the sound

When you increase the frequency of a sound wave you

• increase the volume of the sound

• decrease the volume of the sound

• increase the pitch of the sound

• decrease the pitch of the sound
