Answer:
(i) Ultraviolet
(ii) γ-rays
Explanation:
(i) As it has a higher frequency, the more energetic rays are ultraviolet. Since, it is an electromagnetic radiation, so it is a self-propagating electromagnetic wave that has no mass and no charge. Due to the higher frequency, more power arrives with ultraviolet light per packet (photon) than with the infrared radiation.
(ii) Gamma rays ( γ-rays) are nuclear decline radiation when a nucleus transitions from an excited state of energy to a lower state of energy. Usually, gamma rays are frequency waves greater than 10`19 Hz. We have high energy (over 104 eV per photon) and very short wavelengths (less than 10`−14 m).
