What are the three important characteristics of simple waves mentioned in the passage?

• Wavelength, frequency, amplitude

• Crest, trough, height

• Speed, direction, color

• Intensity, duration, pitch

How is wavelength measured according to the passage?

• From crest to crest or trough to trough

• From the start to the end of a wave

• From the highest point to the lowest point

• From the beginning of a wave to the shore

What happens to light waves during a sunset, as described in the passage?

• Shorter wavelengths are scattered, allowing red and orange light to reach the eyes

• All wavelengths are absorbed by the atmosphere

• Longer wavelengths are scattered, making the sky blue

• Light waves stop traveling

What is the unit of measurement for wave frequency?

• Hertz

• Decibels

• Meters

• Watts

How can the frequency of sound waves produced by a violin be increased?

• By tightening the strings

• By loosening the strings

• By playing faster

• By using a larger bow

What does amplitude represent in a wave?

• The maximum height or depth from its rest position

• The speed of the wave

• The color of the wave

• The direction of the wave

What is the effect of throwing a boulder into a pond compared to a pebble, according to the passage?

• The boulder creates high-amplitude waves

• The boulder creates low-amplitude waves

• The boulder stops the waves

• The boulder creates no waves
