Question

suppose the opera station broadcasts at 90.5MHz and the rock and roll station broadcasts at 107.1MHz. 1.which stations signal has waves with longer waveslength? 2.which stations signal has waves with higher energy

Answer 1

E=hv

h=plancks constant
v=frequency

Answer 2

also, \[\nu=\frac{ c }{ \lambda } \]

v= frequency
c= speed of light
lambda = wavelength
