Vedclass · Answer

(B) green leaf contains pigments that reflect green light and absorb other wavelengths in the visible spectrum. When white light falls on a green leaf,it reflects the green component,making the leaf appear green. The wavelength of green light typically ranges from $0.495 \,\mu m$ to $0.570 \,\mu m$. The incident laser light has a wavelength of $0.6328 \,\mu m$,which corresponds to the red region of the spectrum. Since the leaf does not reflect this wavelength,it absorbs the incident laser light. Because no light is reflected back to the observer,the leaf appears black.
