Compare and contrast mechanical waves and electromagnetic waves. How are they different? Give an example of each
Mechanical waves (sound) needs a medium to travel through while electromagnetic (light) waves do not need a medium and can travel through a vacuum.

Describe the principles of superposition (interference)
Superpostion happens when two haves interact and overlap creating areas of interference. Where these waves are in phase they create Constructive interference, when they are out of phase they create destructive interference.

Distinguish between longitudinal waves and transverse waves?
Longitudinal waves are compression waves where particles move parallel to wave motion.
While transverse waves have particle motion that moves perpendicular to wave motion.

How is the angle of incidence related to the angle of reflection when a wave bounces off a flat object like a mirror?
the angle of incidence is the same as the angle of reflection
500
Which band of the electromagnetic spectrum has the lowest frequency? Shortest wavelength?
radiowaves; gamma rays
500
What is the Doppler effect? Use an an example to help explain you answer
The doppler effect is an observed change in frequency when there is relative motion between the source of waves and an observe. This is seen at the race track when racecars pass by. The frequency is high as the car approaches and decreases as it passes by.
