What is the Doppler Effect?

• A change in frequency due to the relative motion of a wave source and an observer

• When a wave overlaps with another wave

• When a wave bounces off of another object

• When a wave bends due to traveling through a different medium

• Observer B

• There's no difference

True or false: as you move along the spectrum, radio to gamma waves, the wavelengths decrease in size (get smaller)

• true
• false

A wave with a large wavelength will have a ______ frequency and _____ energy

• high, low
• high, high
• low, high
• low, low

Tags

NGSS.HS-PS4-1

Which has the LONGEST wavelength and, therefore, the lowest frequency/energy

• Gamma Rays
• Radio Waves
• Visible Light
• Infrared rays

Tags

NGSS.HS-PS4-1

Which has the SHORTEST wavelength and, therefore, the highest frequency/most energy

• Radio waves
• Ultraviolet Rays
• Gamma Rays
• X-rays

Which section of the spectrum is the ONLY one we can see?

• X-rays
• Visible Light
• Gamma Rays
• Ultraviolet Rays

How are electromagnetic waves different from other waves? 

• They have very short wavelengths 
• They transmit energy instead of matter 
• They can travel through empty space
• They can change direction by reflection 

As the frequency of an electromagnetic wave increases, the amount of energy in that wave...

• increases.
• decreases.
• stays the same.
