X-rays of wavelength equal to 0.134 nm give a first order diffraction from the surface of a - crystal when the value of `theta` is `10.5^(0)`, then the distance between the adjacent planes in the crystal is `(sin 10.5^(@)=0.1822)`

Explanation

To solve the problem of finding the distance between adjacent planes in a crystal using X-ray diffraction, we can follow these steps:

### Step 1: Identify the given values
- Wavelength of X-rays (λ) = 0.134 nm
- Angle of diffraction (θ) = 10.5°
- Order of diffraction (n) = 1 (since it is first order)

### Step 2: Write down the formula for the distance between adjacent planes
