OpenStudy (anonymous):

is that a sinusoidal wave?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

alright.. why are points a, d and f are horizontal lines? raen't they supposed to be points?

OpenStudy (anonymous):

idk thats just the graph it gave me

OpenStudy (anonymous):

alright.. do you know the formula to calculate the energy of a wave?

OpenStudy (anonymous):

For wave that is not an electromagnetic wave, energy is given by:\[E=\frac{ 1 }{2 } \mu \omega ^{2}A ^{2}\lambda \]where μ is the mass density of the wave medium; ω is the angular frequency for the wave; A is the wave amplitude; and λ is the wavelength.

OpenStudy (anonymous):

In general terms:\[E∝A ^{2}\]
