Answer:
1/3 times.
Explanation:
Let V₀ be the peak voltage .
IR ( rms ) = ( V₀ / √2 R )
R is value of resistance
IC = ( V₀ ωC / √2 )
( 1 / ωC is reactance of capacitance in ac circuit )
=
When frequency is tripled angular frequency will also be tripled
hence the ratio becomes 1/3 times.
λ = 5.7 X 10⁻⁷m
On using quantum dot, it is 351
<u>Explanation:</u>
Given-
Frequency, f = 5.20 x 10^14 Hz
Speed of light, c = 3 X 10⁸ m/s
Wavelength, λ = ?
We know,
λ f = c
λ = c / f
λ =
λ = 5.7 X 10⁻⁷m
Dot = 2 X 10⁻⁴
So,
2 X 10⁻⁴ / 5.7 X 10⁻⁷m = 351
