Answer:
1.3.
Explanation:
From the question given above, the following data were obtained:
Sine of incident angle (Sine i) = 0.217
Sine of refracted angle (Sine r) = 0.173
Refractive index (n) =?
From snell's law, the Refractive index is simply defined as the ratio of the sine of the incident angle to sine of the refracted angle. Mathematically, it is expressed as:
Refractive index = Sine of incident angle / sine of refracted angle
n = Sine i / Sine r
With the above formula, we can obtain index of refraction as shown below:
Sine of incident angle (Sine i) = 0.217
Sine of refracted angle (Sine r) = 0.173
Refractive index (n) =?
n = Sine i / Sine r
n = 0.217 / 0.173
n = 1.3
Thus, the index of refraction is 1.3.
Answer:
This equation is based on twin paradox - a phenomena where one of the twin travels to space at a speed close to speed of light and the other remains on earth. the twin from the space on return discovers that the one on earth age faster.
Solution:
= 10 years
v = 0.8c
c = speed of light in vacuum
The problem can be solved by time dilation equation:
(1)
where,
t = time observed from a different inertial frame
Now, using eqn (1), we get:
t = 16.67 years
The age of the twin on spaceship according to the one on earth = 25+16.67 =41.66 years
