Question
Which among the following transmits the highest amount of light that falls on it?
- Tinted glass
- Frosted glass
- Glass slab
- Wooden block
Hint:
A cuboidal-shaped piece of glass transmits the highest amount of light that falls on it
The correct answer is: Glass slab
When a ray of light from air hits a glass plate, it slows down when it hits a dense medium. Since the frequency must be kept constant to save energy (energy depends only on frequency), the wavelength of light changes. Wavelength is reduced by a factor called the refractive index of the medium.
