Answer:
The current pass the is
Explanation:
The diagram for this question is shown on the first uploaded image
From the question we are told that
The voltage is
The first resistance is
The second resistance is
Since the resistors are connected in series their equivalent resistance is
Substituting values
Since the resistance are connected in serie the current passing through the circuit is the same current passing through which is mathematically evaluated as
Substituting values
Answer: 430 nm.
Explanation:
The relation of wavelength and frequency is:
Formula used :
where,
= frequency =
= wavelength = ?
c = speed of light =
Now put all the given values in this formula, we get
Thus the wavelength (in nm) of the blue light emitted by a mercury lamp is 430 nm.
