When two waves meet and combine to form a wave with a larger amplitude, this is called:

• Destructive interference

• Constructive interference

• Reflection

• Refraction

The bending of light as it passes from air into water is an example of:

• Reflection

• Refraction

• Diffraction

• Interference

The Doppler Effect occurs because:

• The speed of sound changes when the source moves.

• The frequency of the waves changes when the source or observer moves.

• The wavelength of waves becomes constant regardless of motion.
