Answer:

C_1=7.23pF\ and\ C_2=2.19pF

Explanation:

Let the two capacitance are C_1\ and\ C_2

It is given that when capacitors are connected in parallel their equvilaent capacitance is 9.42 pF

So C_1+ C_2=9.2--------EQN 1

And when they are connected in series their equivalent capacitance is 1.68 pF

So \frac{1}{C_1}+\frac{1}{C_2}=\frac{1}{1.68}

\frac{C_1+C_2}{C_1C_2}=\frac{1}{1.68}

C_1C_2=1.68\times 9.42=15.8256pF

C_1-C_2=\sqrt{(C_1+C_2)^2-4C_1C_2}=\sqrt{9.42^2-4\times 15.8256}=5.0432pF-----EQN

On solving eqn 1 and eqn 2

C_1=7.23pF\ and\ C_2=2.19pF

A source emits monochromatic light of wavelength 495 nm in air. when the light passes through a liquid, its wavelength reduces t
Katyanochek1 [597]
By definition, the refractive index is
n = c/v
where c =  3 x 10⁸ m/s,  the speed of light in vacuum
v = the speed of light in the medium (the liquid).

The frequency of the light source is
f = (3 x 10⁸ m/s)/(495 x 10⁻⁹ m) = 6.0606 x 10¹⁴ Hz

Because the wavelength in the liquid is 434 nm = 434 x 10⁻⁹ m, 
v = (6.0606 x 10¹⁴ 1/s)*(434 x 10⁻⁹ m) = 2.6303 x 10⁸ m/s

The refractive index is (3 x 10⁸)/(2.6303 x 10⁸) = 1.1406
