Question

is refraction possible without reflection explain​

Answer 1

Answer:

Not always, no. If you have a material with a smooth variation of index of refraction, like in a graded-index (aka GRIN) lens, then you can bend the light as it passes through with without reflection. One can argue that there has to be some point where the index changes, and there’s no such thing as an infinitesimal change in real systems, I suppose, but the effect is close enough as to make it a distinction without a difference.

More directly, there is also a condition for Transmission / Reflection known as where P-polarized light (electric ray in same plane as surface normal and incident ray), at the angle theta = arctan (n2/n1), there will be perfect, 100% transmission from the first media to the other.

Answer 2

Answer:

yes

Explanation:

example

in refraction we need two medium

but in reflection we need only one medium
