a student is exploring mechanical and electromagnetic waves compiling a list of questions for her investigation into the properties of each wave type. which of the following questions would NOT aid her in learning about properties of both mechanical and electromagnetic waves?
a. what is the frequency of the wave?
b. what is the wave speed in a vacuum?
c. what is the amplitude of the wave?
d. what is the wavelength of the wave?
b. what is the wave speed in a vacuum?
The speed of mechanical waves (such as sound waves) depends on the medium through which they travel, whereas electromagnetic waves (such as light waves) always travel at the same speed in a vacuum (the speed of light). Therefore, asking about the wave speed in a vacuum would not provide information about both mechanical and electromagnetic waves.
