Why does green light slow down more than orange light does when passing through an object?

Green light has smaller wavelength than that of orange light.

Explanation:

The wavelength of green light is 510 nm ,while that of orange light is 590 nm.

According to equation

v=f*λ

v∞λ

velocity or speed is directly proportional to wavelength,hence green slows more than orange light because wavelength of green light is smaller than that of orange light.

b would be the answer

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

in four significant figures
