All waves on the electromagnetic spectrum travel at the same speed in a vacuum. the speed of these waves in a vacuum is 3x10 8 m/s. as the wavelength of a wave doubles, how does the speed and frequency of the wave change?

the real answer is A the speed remains the same and the frequency halved hope this helps

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.

you get 2.3=1.21*\frac{a}2 or 4.6=1.21a or a=3.802 (b)
