Ответ:
4.(615384)Hz
Explanation:
Firstly, let's take a note that the speed of light is much higher than 30m/s, on the other hand visible light has wavelengths measured in nanometers, so I assume we're just supposed to assume the values in the question for the purpose of solving it.
If a wave moves through a point with speed v and has wavelength l, In each second we observe v/l cycles - and cycles per second is the frequency!
F = 30m/s / 6.5m = 4.(615384)/s = 4.(615384)Hz
Ответ:
Explanation:
v=fh, where v is velocity
f is frequency
h is wavelength
hence the frequency=velocity/wavelength
=30/6.5
=4.61Hz
Ответ:
No there won't be.
Explanation:
An insulator does not conduct electricity readily. An insulator that is charged at one end will have the charges remain at that end, since it does not allow the free flow of charges through it. If you touch the other end of the insulator that is void of electric charges, there would be no charge transfer between you and the insulator, and hence no electric shock.
