Now! what best describes violet light? a. is a form of infrared light b. is a form of ultraviolet light c. has the longest wavelength d. has the shortest wavelength

The answer is D. In the visible spectrum of light, ultraviolet light has the most energy while red has the least energy. Violet light has shorter wavelengths and higher frequency. This is converse to red light that has longer wavelengths but lower frequency.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
