Please help Your parents are having a discussion in the other room about what reward to give you for getting all A's on your latest report card. You can't hear them, but then you remember something from your Physical Science class. You put a glass to the wall and your ear to the other end. Now you can hear them. The glass helps you hear your parents by:

A.) focusing the wave energy into your ear.

B.) Conducting sound waves better than air.

C.) Interfering with unwanted sound waves.

D.) Reflecting sound waves better than the wall.

Select light for the type of wave, adjust the wavelength so that the light is red, and increase the amplitude of the light to the max. then, select the start button at the source location to begin producing the waves. light is a form of electromagnetic wave, containing oscillating electric and magnetic fields. the wave amplitude detector mentioned above shows how the electric field oscillates in time at the location of the probe. the amplitude of the wave at the location of the probe is equal to the maximum electric field measured. how does the amplitude of the wave depend on the distance from the source?
