Question 5
|
How much bandwidth is there in 1 micron of spectrum at a wavelength of 1 micron ?
|
300 MHz
|
|
|
3 GHz
|
|
|
300 THz
|
|
|
30 KHz
|
Question 5 Explanation:
According to formula, Δf=c∗Δλ / (λ*λ)
where,
Δf is the bandwidth range,
c is the light speed,
Δλ is the wavelength range,
λ is a certain wavelength. ,
Δλ = 3*10e8 * 0.1*10e-6 / (10e-6 * 10e-6)
= 3*10e13Hz
= 30THz
where,
Δf is the bandwidth range,
c is the light speed,
Δλ is the wavelength range,
λ is a certain wavelength. ,
Δλ = 3*10e8 * 0.1*10e-6 / (10e-6 * 10e-6)
= 3*10e13Hz
= 30THz
Correct Answer: C
