A beam of white light goes from air into the water droplet at an incidence angle. The angle between the red (660 nm) and violet (410 nm) parts of the refracted light is 0.19°.
What is white light?The white light is the ray coming directly from the Sun. When it strikes any glass object, an spectrum of colors with different wavelength is formed.
Given is the angle of incidence, i = 36.2°, the refractive index of water for red light is 1.331 , the refractive index of water for violet light is 1.340 and refractive index of air is 1.
Using the Snell's law, the angle of refraction of red light will be
1.331 x sin r(R) = 1 x sin 36.2
r(R) = 26.342°
Using the Snell's law, the angle of refraction of violet light will be
1.340 x sin r(R) = 1 x sin 36.2
r (V) = 26.152°
Difference in the angle of refraction of red and violet light is
r(R) - r (V) = 26.342 - 26.152 = 0.19°
Thus, the angle between the red (660 nm) and violet (410 nm) parts of the refracted light is 0.19°.

An engineer is designing a television screen. the screen is shaped like a rectangle with a length of 43.6 inches. the ratio of the length of the rectangle to its width must be 16:9. what is the approximate length of the diagonal of the screen?
By using the given ratio, we will see that the diagonal measures 50 inches.
How to get the diagonal of the screen?First, we know that the ratio between length and width is 16:9, and the length is 43.6 inches, then the width will be:
W = (9/16)*43.6 inches = 24.5 in
Now, the diagonal will be equal to the hypotenuse of a right triangle with catheti of 43.6 in and 24.5 in, by using Pythagorean's theorem we get:
[tex]D = \sqrt{(43.6in)^2 + (24.5in)^2} = 50 in[/tex]

The correct statement about the circumference (C) and the height (h) is gotten as; C > h
How to find the circumference of the cylinder?The formula for circumference of a cylinder is;
C = 2πr
Now, we are not given the radius of the cylinder but we are told that there are 3 balls that fit perfectly into the cylindrical canister. Each having a diameter of 1.68 inches.
Thus;
Radius; r = d/2 = 1.68/2 = 0.84 inches
Height of cylinder will be;
h = 3d = 3 * 1.68
h = 5.04 inches
Circumference; C = 2π * 0.84 = 5.28 inches. Thus;
C > h

Of the twenty times in this experiment the following are prime (3,5,2,7,3,7,2,2,7,3,3,5) or 12 of the twenty
12/20 = 6/10 = 60%
So 60% is the experimental probabilty.
The theoretical probability given that there are four prime numbers (2,3,5,7) out of 8 on the dice should be 50% because 1/2 of the numbers are prime.
