• 4

The illustration shows a wave. The wave's wavelength is the distance between points -

• 1 and 2

• 1 and 4

• 2 and 3

Which of the following is true about the speed of transverse (light) waves compared to longitudinal (sound) waves in the same medium?

• Transverse waves always travel faster than longitudinal waves.

• Longitudinal waves always travel faster than transverse waves.

• The speed depends on the medium and the frequency of the wave.

• The speed is the same for both types of waves in any medium.

How does the amplitude of a sound wave affect the loudness of the sound?

• The higher the amplitude of the wave, the louder the sound.

• The lower the amplitude of the wave, the louder the sound.

• The amplitude of the wave and the loudness of the sound are not related.

• The relationship between the amplitude of the wave and the loudness of the sound is complex and not fully understood.

Which of the following best describes the concept of resonance?

• When two sound waves with different frequencies combine to form a single wave with a new frequency.

• When a sound wave is reflected back on itself and cancels out.

• When a sound wave interacts with an object and causes it to vibrate at its natural frequency.

• When a sound wave is absorbed by an object and does not reflect back.

Which of the following is an example of a sound wave interacting with a medium to produce a reflection?

• A guitar string vibrating and producing a sound wave.

• A person speaking into a microphone and producing an electrical signal.

• A sound wave traveling down a hallway and bouncing off the walls.

• A car driving by and creating a disturbance in the air.

Which of the following colors of light has the highest frequency?

• Red

• Yellow

• Green

• Blue

Which of the following statements about the electromagnetic spectrum is true?
