Question

in what two respects can we regard gamma radiations and visible light as being similar to each other​

Answer 1

Answer:

Both gamma radiation and visible light are electromagnetic radiation and are, in that sense, variants of the same thing. Gamma rays just have much higher frequencies. Since the energy of a photon increases as its frequency increases, the photons that comprise gamma rays can be much more destructive than those in the visible light frequencies when they interact with matter.

It might be worth mentioning that, of the usually discussed forms of radiation—alpha, beta, and gamma—only gamma radiation consists of photons and hence are in the electromagnetic spectrum. Alpha and beta radiation are both made up of particles.

Also, gamma rays can be emitted when particles and antiparticles, such as an electron and a positron, meet and annihilate each other. As such things go, this is a pretty big dollop of energy.
