If a wave transfers from one medium to another medium with different properties, which statement is true?(1 point)
Responses
The period and the speed of the wave change proportionally.

Two similar waves are traveling through the same medium. Wave A has a frequency that is 3 times that of wave B.
How do their wavelengths compare?

λA=λB
lambda sub cap A is equal to lambda sub cap b
λA=19λB
lambda sub cap A is equal to 1 ninth lambda sub cap b
λA=13λB
lambda sub cap A is equal to 1 third lambda sub cap b
λA=3λB
λA=13λB
(lambda sub cap A is equal to one-third lambda sub cap b)
