Light of wavelength `6000 Å` in air enters a medium of refractive index 1.5. What will be its wavelength in the medium ?

Explanation

To find the wavelength of light in a medium with a refractive index of 1.5, we can follow these steps:

### Step 1: Understand the relationship between wavelength, frequency, and speed of light
The speed of light (c) in a vacuum is related to its wavelength (λ) and frequency (f) by the equation:
\[ c = \lambda \cdot f \]

### Step 2: Calculate the speed of light in the medium
The refractive index (n) of a medium is defined as the ratio of the speed of light in vacuum (c) to the speed of light in the medium (v):
