Answer:
n = 4 x 10¹⁸ photons
Explanation:
First, we will calculate the energy of one photon in the radiation:
where,
E = Energy of one photon = ?
h = Plank's Constant = 6.625 x 10⁻³⁴ J.s
c = speed of light = 3 x 10⁸ m/s
λ = wavelength of radiation = 567 nm = 5.67 x 10⁻⁷ m
Therefore,
E = 3.505 x 10⁻¹⁹ J
Now, the number of photons to make up the total energy can be calculated as follows:
<u>n = 4 x 10¹⁸ photons</u>
Answer:
Part a)
Rate of charge flow is known as electric current
Part b)
Average current flow is
Part c)
As we know that current density is current per unit area
Explanation:
As we know that angular frequency of rotation is
now by basic definition of electric current
Part a)
Rate of charge flow is known as electric current
so here we have
Part b)
here we know that
now we have
Part c)
As we know that current density is current per unit area
So we have
