(a) Waves P and Q have the same frequency, but wave P has twice the wavelength of wave Q

(b) Waves Q and R have the same wavelength, but wave R has twice the frequency of wave Q.

(c) Wave T shows a steady frequency but changing amplitude

(d) Wave S shows a steady amplitude but changing frequency

(e) Waves Q and R have a low amplitude and a steady frequency

HOPE THESE ARE RIGHT

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.
