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°

Usually
pH scale measures from 1 to 14
Purple colour indicates pH as 14
Hence it's an base
But it doesn't react with metals to form salts and hydrogen gas.
It's sure it's non metal but not base
One possibility is that it's Carbon compound or Graphite compound which reacts like base but a metal in real sometimes
