Consider the following statements:
1. Ultraviolet light has a higher energy and shorter wavelength than visible light
2. Orange light has a lower frequency and longer wavelength than blue light
Which among the above is / are correct?

Answer: [C] Both 1 & 2

Gamma rays and X-rays are very high-energy, short-wavelength radiations. Ultraviolet light has a higher energy and shorter wavelength than visible light. Within the visible spectrum, the colors are—in order of increasing frequency—ROYGBV, so orange light (“O”) has a lower frequency—and thus a longer wavelength—than blue light (“B”).
