Bill Nye: Waves

What is a fundamental characteristic of waves?

• They are stationary.

• They are physical objects that move.

• They are a means by which energy travels.

• They only exist in water.

What is the term for the distance between two consecutive peaks or troughs of a wave?

• Frequency

• Amplitude

• Wavelength

• Velocity

What happens to the wavelength of a wave as its frequency increases?

• It increases.

• It decreases.

• It remains the same.

• It becomes unpredictable.

What property of a wave is controlled by an amplifier's volume knob and indicates the 'size' of the wave?

• Frequency

• Wavelength

• Amplitude

• Pitch

What distinguishes different types of electromagnetic waves from one another?

• Their speed of travel

• Their ability to carry sound

• Their wavelength

• Their source of origin

What kind of frequency do X-ray waves have?

• High Frequency

• Low Frequency

Which of the following are key properties of waves that can be measured?

• Color, density, and temperature.

• Wavelength, frequency, and amplitude.

• Mass, volume, and pressure.

• Speed, direction, and acceleration.

What is a primary characteristic of waves as demonstrated by the boat and the spring?

• Waves always travel in a straight line.

• Waves can carry energy from one place to another.

• Waves only occur in water or springs.

• Waves cause objects to move in a circular motion.

How do sound waves travel through the air?

• Air molecules move up and down in a transverse motion.

• Air molecules bump into each other, creating areas of compression and spreading.

• Sound waves create a vacuum that pulls air molecules along.

• Air molecules vibrate in a circular pattern.
