Waves

What is a wave's amplitude?

• The distance between two crests
• The number of waves per second
• Half the distance between a crest and trough

Which statement best describes the relationship between frequency and wavelength?

• They are inversely proportional
• They are directly proportional
• They are always equal

. What occurs during wave reflection?

• Waves spread around obstacles
• Waves combine with other waves
• Waves bounce off surfaces

What is a node in a wave?

• The highest point of a wave
• The lowest point of a wave
• Where the wave crosses the resting line

What happens to wavelength when frequency increases?

• Wavelength stays the same
• Wavelength increases
• Wavelength becomes shorter

How is wavelength measured?

• From crest to trough
• From the highest to lowest amplitude
• From crest to crest or trough to trough

What is frequency in waves?

• The number of waves passing a point in a given time
• The distance between two crests
• The height of the wave

What happens during wave diffraction?

• Waves spread out around obstacles
• Waves bounce off surfaces
• Waves combine together

What type of wave is a sound wave classified as?

• Electromagnetic wave
• Mechanical wave
• Light wave

In a longitudinal wave, how does the medium move in relation to the wave?

• Perpendicular to the wave
• In random directions
• In the same direction as the wave
