Answer:
Electromagnetic waves are reflected
Explanation:
Reflection of light (and other forms of electromagnetic radiation) occurs when the waves encounter a surface or other boundary that does not absorb the energy of the radiation and bounces the waves away from the surface. ... This concept is often termed the Law of Reflection.
Answer:
(a) 42°
Explanation:
According to the law of reflection:
Angle of incidence = Angle of reflection
So, angle of reflection = 62°
Angle of incidence = 62°
For refraction,
Using Snell's law as:
Where,
is the angle of incidence ( 62.0° )
is the angle of refraction ( ? )
is the refractive index of the refraction medium (water, n=1.33)
is the refractive index of the incidence medium (air, n=1)
Hence,
Angle of refraction = 
= 42°
