Introduction to Waves

What word describes the distance between 2 crests or 2 troughs?

• amplitude
• energy
• resting point
• wavelength

How are frequency and energy related? 

• lower frequency = more energy
• lower frequency = less energy
• Frequency and energy are the same
• Frequency and energy are not related

Which type of waves can travel through matter AND empty space? 

• mechanical waves
• all waves
• electromagnetic waves
• no waves

Which waves travel PARALLEL to the wave's direction? 

• transverse waves
• longitudinal waves

• reflection
• refraction
• diffraction
• interference

Two waves combine and cancel each other out.  What does this describe? 

• constructive interference
• destructive interference
• diffraction
• refraction

Two waves combine to make a wave with a larger amplitude.  What does this describe? 

• reflection
• refraction
• destructive interference
• constructive interference

You reach into a lake to pick up a stone but it's in a different spot than it appears.  What does this describe?
