Ahorizontal parallel-sided plate of glass having a refractive index of 1.56 is in contact with the surface tnk. a ray coming from above in air makes an angle of incidence of 32.5. with the normal to the top surface of the glass. take refractive index of air 1 a) what is the angle of refraction on glass surface? (5 pts) of wa er i b) what is the critical angle of gla ss-water surface as explained above?

(I). The angle of refraction on glass surface is 20.12°

(II). The critical angle of glass-water surface is  61.0°.

Explanation:

Given that,

Refractive index of glass = 1.56

Angle = 32.5

(I). We need to calculate the angle of refraction on glass surface

Using Snell's law

Put the value into the formula

(II). We need to calculate the critical angle of glass-water surface

Using formula of critical angle

Hence, (I). The angle of refraction on glass surface is 20.12°

(II). The critical angle of glass-water surface is  61.0°.

answer; i believe the correct answer is (40,000 j) good luck

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
