Question

What is the meaning of medium in light ch. Class 10​

Answer 1

Answer:

Medium is a substance through which a wave(in this case LIGHT) can propagate or travel through.

Answer 2

Answer:

Assuming “radiation” is “light propagation”. It means that the propagation of certain wavelengths is assisted or mediated by the electrons and atoms of the bulk medium. This is why “violet light is propagated more slowly” than is red… you have to grab a deeper electron, and/or boost it harder.
