Answer:
Explanation:
from snells law
sin(i)/sin(r) = refractive index
r = 90°
sin(i) = sin90°x 1.6
sin(i) = 1 x 1.6
angle of incidence = arcsin(1.6)
since sin90° = 1
hence,
angle of incidence = 36.86°
False

Answer:
The temperature is (-19.67) degrees Celsius.
Explanation:
It is required to find the temperature if the speed of sound through air is measure to be 319 m/s.
The speed of sound in terms of temperature is given by :
T is temperature and v = 319 m/s
So, the temperature is (-19.67) degrees Celsius.
