Answer: Comparing infrared and ultraviolet, ''we can say that infrared has longer wavelength and lower photon energy''
Answer:
360 V
Explanation:
We can use the transformer equation:

where
is the primary (input) voltage
is the number of turns in the primary coil
is the secondary (output) voltage
is the number of turns in the secondary coil
In this problem,

Substituting into the equation, we can find the output voltage:

Dont really understand what youre asking but switches can be used to turn things on and off.
