The question is incomplete. You dis not provide values for A and B. Here is the complete question
Light in the air is incident at an angle to a surface of (12.0 + A) degrees on a piece of glass with an index of refraction of (1.10 + (B/100)). What is the angle between the surface and the light ray once in the glass? Give your answer in degrees and rounded to three significant figures.
A = 12
B = 18
Answer:
18.5⁰
Explanation:
Angle of incidence i = 12.0 + A
A = 12
= 12.0 + 12
= 14
Refractive index u = 1.10 + B/100
= 1.10 + 18/100
= 1.10 + 0.18
= 1.28
We then find the angle of refraction index u
u = sine i / sin r
u = sine24/sinr
1.28 = sine 24 / sine r
1.28Sine r = sin24
1.28 sine r = 0.4067
Sine r = 0.4067/1.28
r = sine^-1(0.317)
r = 18.481
= 18.5⁰
The frequency of the electromagnetic wave is 9.55 × 1014 Hz and it is classified as ultraviolet.
<h3>What is meant by electromagnetic waves?</h3>
Electromagnetic waves are forms of energy that are invisible and travel throughout the universe. However, some of the effects of this energy are visible. The light that we see is a component of the electromagnetic spectrum.
Electromagnetic waves, or EM waves, are produced by vibrations between an electric field and a magnetic field. In other words, electromagnetic waves are made up of oscillating magnetic and electric fields.
<h3>How do you calculate the speed of an electromagnetic wave?</h3>
The wavelength and frequency of any periodic wave are used to calculate its speed. v = λf.
In free space, the speed of any electromagnetic wave is equal to the speed of light, c = 3 
108 m/s.
The frequency of the electromagnetic wave is 9.55 × 1014 Hz and it is classified as ultraviolet.

Answer:
An ion is an atom or group of atoms with a positive or negative charge. Ions form when atoms lose or gain electrons to obtain a full outer shell: metal atoms lose electrons to form positively charged ions non-metal atoms gain electrons to form negatively charged ions.

Answer:
Shortest time = 58.18 × 10^(-6) s
Explanation:
We are given;
s(x,t) = 5.00 nm cos((60.00 m^(−1)x) − (18.00 X 10³ s^(−1)t))
Let us set x = 0 as origin.
Now, for us to find the time difference, we need to solve 2 equations which are;
s(x,t) = 5.00 nm cos((60.00 m^(−1)x) − (18.00 X 10³ s^(−1)t1))
And
s(x,t) = 5.00 nm cos((60.00 m^(−1)x) − (18.00 X 10³ s^(−1)t2))
Now, since the wave starts from maxima at time at t = 0, the required time would be the difference (t2 - t1)
Thus, the solutions are;
t1 = (1/(18 × 10³)) cos^(-1) (2.5/5)
And
t2 = (1/(18 × 10³)) cos^(-1) (-2.5/5)
Angle of the cos function is in radians, thus;
t1 = 58.18 × 10^(-6) s
t2 = 116.36 × 10^(-6) s
So,
Required time = t2 - t1 = (116.36 × 10^(-6) s) - (58.18 × 10^(-6) s) = 58.18 × 10^(-6) s
Answer:
The Production Function is the relationship between the quantity or variables of output and the different inputs quantities used in the production process.
Explanation:
Generally in quality, production or any business, we need to know what is the output with respect to different input variables. Suppose if an output is about bottle produce per hour, then we look at the inputs such as temperature, raw material/inventory, power supply, manpower, etc which are needed to produce bottle. any changes, for example in temperature could change the production rate.
Furthermore, a graph is made to see the production function.
