• Question: Would electromagnetic waves such as gamma refract the same way light does in mediums?

      Yes, because light is an electromagnetic wave! Gamma rays (and microwaves, radiowaves UV…) is all just light that you **can’t see** – so behave in the same way as the light you see when you do experiments with ray boxes and prisms 🙂

      As Mary says, X-rays and gamma particles are EM waves and so are subject to all wave phenomena like refraction and diffraction. However, the dominant interactions of these very short wavelength/high frequency waves with matter are very different from those of visible light.

      For example, the speed of gamma rays is hardly affected by passing through matter so the refractive index is always extremely close to one. Refraction effects are therefore very difficult to observe.
