Question

Why can gamma rays penetrate solids?

Answer 1

Gamma rays have low mass.
Gamma rays have high mass.
Gamma rays have low velocity.
Gamma rays have high velocity.

Answer 2

gamma rays have very high energy because they move at high velocity

Answer 3

so the last answer

Answer 4

ty

Answer 5

looking first at different types of EM, gamma rays, visible light and radio waves all travel at the speed of light. The **same** speed. That gamma rays and radio waves pass through an opaque solid whereas light cannot cannot therefore turn on their velocity alone, ....

...and their (per photon) energy for that matter is driven by frequency/wavelength as Energy is \(E = h f\). So visible light falls, in terms of energy per photon, between gamma rays and radio waves but both the latter "can" pass through an opaque solid.

In addition gamma, light and radio waves photons have zero mass.

If OTOH you're actually comparing gamma to alpha and beta, well the above holds true for gamma but then you are comparing apples and pears. So you could use classical physics and argue that alpha and beta are big clunky things that are relatively slow compared to the speed of light, and that they must therefore slow down more in a crowd of other "things"

but photons aren't really things that collide in that sense.

none of those poss answers make much sense in that context
