A light wave of frequency `5xx10^14 Hz` enters a medium of refractive index `1.5`. In the velocity of the light wave is ….. And its wavelength is ……

Explanation

To solve the problem, we need to find the velocity of the light wave in the medium and its wavelength. Let's go through the steps one by one.

### Step 1: Calculate the velocity of light in the medium
The speed of light in a medium can be calculated using the formula:
\[ v = \frac{c}{n} \]
where:
- \( v \) is the speed of light in the medium,
- \( c \) is the speed of light in vacuum (approximately \( 3 \times 10^8 \) m/s),
