Answer:
A. Prism
Explanation:
In the experiment we are able to isolate different wavelengths by shining the light through a prism, which separates the different wavelengths through refraction.
Newtons
R=V/I
R= 2
R = 10V/5A
R = 2ohms
200 volts
Ohm's Law: V = IR
I = 10 A
R = 20 ohms
V = (10)(20) = 200 volts
