Applications of Waves Test Review APEX

Which type of matter is likely to absorb the most sound waves?

• Metal door

• Loudspeaker

• Hot air

• blanket

In which situation are waves transmitted?

• A camp fire lights up a cave.

• Ice cream melts on a hot day.

• Leaves look green in sunlight.

• A curtain blocks light from a window.

Through which material would you expect sound waves to move fastest

• Air

• Iron

• milk

• water

Lightning is seen before its associated thunder is heard. This is because light waves travel faster in air than sound waves do.

Through which material would sound waves move faster than light waves?

• Liquid water

• Helium gas

• Solid bronze metal

• Oxygen gas

What causes a sound wave to echo in an empty house?

• Reflection of waves off smooth walls

• Absorption of waves by rough walls

• The snorkel in the man's mouth appears yellow.

Which observation provides evidence that some kinds of mediums can bend light waves?

• Green plant leaves absorb red light waves found in sunlight.

• Different colors of light refract at different angles when passed through a prism.

• Light waves travel at a speed of about 300,000,000 m/s in empty space.
