Answer: Angle 59 degree
Explanation: Given that the
n1 = 1.0
n2 = 1.5
Øi = 35 degree
From Snell law, which says that
n1/n2 = sinØ1/ sinØ2
Substitute all the parameters into the formula
1/1.5 = sin 35/sinØ2
Cross multiply
Sin Ø2 = 1.5 sin35
SinØ2 = 1.5 × 0.573 = 0.860
Ø2 = sin^-1(0.860)
Ø2 = 59.36 degree
Ø2 = 59 degree ( approximately)
It has angle 59 degree when passing from air to glass
B: Energy lose
i say this because in order to change they lose energy.
magnitude of the net force = mass x acceleraton
= 22 x 2.3
=50.6 N
Mechanical waves travel the fastest in
solids and liquids because the
molecules are more closely packed together than gases, so energy is transferred
from one particle to another particle faster<span>.</span>
