What wavelength would a green glass have?

Most likely between #510" nm"# and #570" nm"#.


My guess is the question is using "green" to describe the "type" of glass, and "green-yellow" to describe its colour.

Basically, we are told that a type of glass (which we will call "green glass") appears green-yellow in colour, and we are asked what wavelengths of light could produce this colour.

According to the light spectrum, the wavelength of green light is around #510" nm"#, and yellow light is around #570" nm"#. So, if an object (like "green glass") appears green-yellow in colour, its wavelength would be somewhere in this range—between #510"-"570" nm"#.
