Answer:
critical angle = 64.79°
ray will not penetrate into the water
Explanation:
given details
refractive index of oil n1 = 1.47
refractive index of water n2= 1.33
incident angle = 71.4 °
= sin^{-1}(\frac{1.33}{1.47}
critical angle = 64.79°
incident angle > critical angle = reflection
incident angle < critical angle = refraction
In this case, 71.4 > 64.79 therefore it will undergo total internal reflection
therefore ray will not penetrate into the water
Answer:
24.7 s
Explanation:
Question is appear to be missing. Found it on google:
"a) If there were no air resistance, how long would it take to fall?"
Solution:
We can solve the problem by using the following equation of motion for a uniform accelerated motion:
where
d = -3000 m is the displacement of the raindrop (negative because in the downward direction)
u = 0 is the initial velocity of the raindrop if we assume it starts from rest
t is the time taken for the fall
a = g = -9.8 m/s^2 is the acceleration of gravity
Solving the equation for t, we find:
