Answer:
When light incident at angle more than critical angle then whole beam of light will get reflected at same angle into the same medium
So correct answer is
Option D
Explanation:
Critical angle is the maximum angle of incidence for which light shows the phenomenon of refraction of light
Here light bends at 90 degree angle when light incident at critical angle
Now if the incident light is more than the critical angle then light will follow the rules of reflection and all light rays will get reflected at same angle as that of angle of incidence
So here we can say that correct answer is
Option D
This sounds like thermal expansion.
Answer:
The answer to question is below
Explanation:
Data
t1 = 0
vo = 4 m/s
a)
d = vot + 
d = 4t + 
b)
c)
= 
t² = 32
t = 5.66 s
d)
d = 4(5.66) + 0.75(5.66)²
d = 22.64 + 24.02
d = 46.67 m
The answer is C. They are a change of pressure that moves through matter
