What is wave interference, and the two types of wave interference?
 
  What will be an ideal response?

Question 2

Show the relationship between wave speed and wave frequency. If the speed of a longitudinal wave is 340 m/s and the frequency is 1000 Hz, what is the wavelength of the wave?
 
  What will be an ideal response?

Answer to Question 1

Answer: Wave interference is the result of two or more waves combining together. When the waves combine in phase, with crests overlapping crests and troughs overlapping troughs, the resulting wave has greater amplitude. This is constructive interference. When crests overlap troughs, cancellation or diminishing of the wave results. This is destructive interference.

Answer to Question 2

Answer: Speed = wave frequency  wavelength. So wavelength = speed/frequency =
(340 m/s)/(1000 Hz) = 0.34 m.
