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.
Answer:
55.92 ohm
Explanation:
R = resistance of the resistor = 50 ohm
f = frequency = 2000 Hz
= Capacitance of first capacitor = 5.0 x 10⁻⁶ F
= Capacitance of second capacitor = 10 x 10⁻⁶ F
= Series combination of capacitance
Series combination of capacitance is given as
= capacitive reactance of series combination
Capacitive reactance of capacitor is given as
ohm
R = resistance of the resistor = 50 Ω
z = impedance of the circuit
Impedance is given as
z = 55.92 ohm
