Answer:
Step-by-step explanation:
To calculate the beam's wavelength in the diamond, we can use Snell's Law, which relates the angle of incidence and the refractive indices of two mediums:
n₁ * λ₁ = n₂ * λ₂
Where:
n₁ = refractive index of the initial medium (air or vacuum)
λ₁ = wavelength in the initial medium (given as 6.05 x 10^(-7) m)
n₂ = refractive index of the second medium (diamond, given as 2.42)
λ₂ = wavelength in the second medium (what we want to find)
Rearranging the equation, we can solve for λ₂:
λ₂ = (n₁ * λ₁) / n₂
Given that n₁ is approximately 1 (refractive index of air or vacuum), we can substitute the values:
λ₂ = (1 * 6.05 x 10^(-7) m) / 2.42
Calculating this expression:
λ₂ ≈ 2.50 x 10^(-7) m
To convert this wavelength to micrometers (µm), we divide by 10^(-6):
λ₂ ≈ 0.25 µm
Therefore, the beam's wavelength in the diamond is approximately 0.25 µm.
