Sound & Light

Sound is a:

• Particle

• Longitudinal Wave

• Transverse Wave

• Amplitude

In soundwaves, compression occurs when:

• The amplitude gets larger

• The air particles are pushed into each other

• The amplitude gets smaller

• The air particles are further apart

Answer explanation

When screaming, Tom's voice is louder than Jerry's. The soundwaves of Tom's voice has a:

• smaller amplitude than Jerry's

• larger amplitude than Jerry's

• smaller frequency than Jerry's

• larger frequency than Jerry's

Which medium does sound travel the fastest in?

• Solids

• Liquids

• Gases

In soundwaves, pitch is defined/affected by:

• Compression

• Amplitude

• Wavelength

• Frequency

Structure 9 is known as the:

In the ear, the ossicles:

• are fluid-filled, spiral structures that convert vibrations to impulses

• are made up of 3 small bones: the hammer, anvil, & stirrup

• runs from the middle of the ear to the back of the nose

• directs soundwaves to the eardrum

Light moves as a:

• trough

• transverse wave

• longitudinal wave

• crest

When moving from air to water, a ray of light will:

• speed up & bend towards the normal

• speed up & bend away from the normal

• slow down & bend towards the normal

• slow down & bend away from the normal

The bending of light is called:
