What inductance must be connected to a 25 p F capacitor in an oscillator capable of generating 410 nm (i.e visible ) electromagnetic waves ? Comment on your answer.

Explanation

To determine the inductance that must be connected to a 25 pF capacitor in an oscillator capable of generating electromagnetic waves with a wavelength of 410 nm, we can follow these steps:

### Step 1: Understand the relationship between wavelength, frequency, and speed of light
The frequency \( f \) of the electromagnetic wave can be related to its wavelength \( \lambda \) using the formula:
\[ f = \frac{c}{\lambda} \]
where \( c \) is the speed of light, approximately \( 3 \times 10^8 \) m/s.
