Question

$Consider two adjacent materials, material 1 has a lower index of refraction than material 2. If an electromagnetic wave moves$

Answer 1

Answer #1

yes . it is true frequency donot change when em wave enters from one medium to another

hence stays the same is correct choice

go with your answer
