waves

Which of the following properties makes a light wave different from all mechanical waves?

• A light wave slows down in a vacuum.

• A light wave is able to transmit energy.

• A light wave exists as a transverse wave.

• A light wave can travel without a medium.

Waves that can travel through a vacuum and do no require a medium are called?

• Transverse Waves

• S-Waves

• Mechanical Waves

• Electromagnetic Waves

Waves that need a medium are called?

• Electromagnetic Waves

• P-Waves

• Mechanical Waves

• Taco Bell

What causes the refraction of a wave?

• the density of the medium changes the speed

• the amount of the medium changes the direction

• the color of the medium changes the speed

• the type of wave changes the direction

Objects appear different in size and shape in a container of water due to ____________________________.

• transmission

• reflection

• absorption

• refraction

When the frequency of a wave decreases, the ____________________________________ of the wave increases.

• wave speed

• amplitude

• wavelength

• Doc McStuffins

Mechanical waves (like sound) cannot travel through...

• metal

• a tree

• empty space (vacuum)

• a door

The two waves have different...

• amplitudes

• speeds

• wavelengths

• frequencies

What happens when you increase the amplitude of a sound?

• it makes the sound louder
• it makes the sound travel faster
• it increases the wavelength of the sound
• it increases the frequency of the sound

What do waves carry from place to place?

• Energy, but not matter or particles
• Energy and matter or particles
• Matter or particles but not energy
• Neither energy nor matter or particles
