Questions & Step-by-Step Solutions
If the wavelength of light in air is 600 nm, what is its wavelength in glass (n=1.5)?
Step 1: Understand that the wavelength of light changes when it moves from one medium (like air) to another medium (like glass).
Step 2: Identify the given values: the wavelength in air (λ) is 600 nm and the refractive index of glass (n) is 1.5.
Step 3: Use the formula to find the wavelength in glass (λ'): λ' = λ / n.
Step 4: Substitute the values into the formula: λ' = 600 nm / 1.5.
Step 5: Perform the division: 600 nm divided by 1.5 equals 400 nm.
Step 6: Conclude that the wavelength of light in glass is 400 nm.
Wavelength and Refraction – The relationship between the wavelength of light in different media, specifically how it changes when light enters a medium with a different refractive index.
