Aray of light strikes a flat block of glass (n = 1.52) of thickness 1.50 cm at an angle of 36.0° with the normal. trace the light beam through the glass, and find the angles of incidence and refraction at each surface. if the angle of incidence at first surface is 36.0° (all angles are measured from the normal), determine the following angles. angle of refraction at first surface

angle of refraction at first surface is 22.74°

Step-by-step explanation:

Given data

thickness = 1.50 cm

n = 1.52

angle = 36.0°

to find out

angle of refraction at first surface

solution

we will apply here  Snells law that is

n1 sinθ1 = n2 sinθ2

θ2 = sin^-1 ( n1/n2) sin θ1

here n1 is 1 and n2 is 1.52 and θ1 = 36.0°

θ2 = sin^-1 ( n1/n2) sin θ1

θ2 = sin^-1 ( 1 / 1.52 ) sin36

θ2 = 22.74°

angle of refraction at first surface is 22.74°

i found the life tables for the year 2012. 

life table of males at age 30. probability of dying between ages x and x+1

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497
