Answer:
(a). The thickness of the glass is 868 nm.
(b). The wavelength is 3472 nm.
Explanation:
Given that,
Refractive index = 1.20
Wavelength = 496 nm
Next wavelength = 386 nm
We need to calculate the thickness of the glass
Using formula for constructive interference
Put the value into the formula
In first case,
.....(I)
In second case,
.....(II)
From equation (I) and (II)
Put the value of m in equation (I)
The thickness of the glass is 868 nm.
(b). We need to calculate the wavelength
Using formula of constructive interference
Put the value into the formula
Hence, (a). The thickness of the glass is 868 nm.
(b). The wavelength is 3472 nm.
The electric power used by the car battery is given by
where
V is the voltage of the battety
I is the current
P is the electric power.
For the battery in our problem, the voltage is V=12.0 V while the current intensity is I=0.5 A, so the power used by the battery is
