Question

jin has four colorful glass bottles on his windowsill. one is red, one is violet, one is green, and one is yellow. the light that passes through which bottle has the lowest frequency? red violet green yellow

Answer 1

Answer: The light passing through Red bottle will have the lowest frequency.

Explanation: Relation between wavelength and frequency follows:

`\\u =(c)/(\lambda )`

As, from the above relation, it is clear that the wavelength and frequency follows inverse relation, so the light having highest wavelength will have the lowest frequency.

From the spectra of visible region, the wavelength of Red light is maximum and hence, it will have the lowest frequency.

Therefore, the light passing through the bottle which is red in color will have the lowest frequency.

Answer 2

The red bottle would have the lowest frequency because red light has the longest wavelengths. The light passing through the violet would have the highest frequency because its wavelengths are the shortest.
