A plate of glass with parallel faces having a refractive index of 1.52 is resting on the surface of water in a tank. A ray of light coming from above in air makes an angle of incidence 36.0 with the normal to the top surface of the glass.

What angle does the ray refracted into the water make with the normal to the surface?

Use 1.33 for the index of refraction of water.

the answer is 48m^2!

step-by-step explanation:

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
