Based on the calculations, the angle relative to the incoming direction is equal to 82°.
<h3>How to calculate the angle?</h3>
Based on scientific records and the information provided, we know that the refractive index of diamond is 2.42 and the incident angle (Ia) is 41°.
Next, we would determine the total refraction angle by applying Snell's law:
n₁sini = n₂sinr
2.41sini = 1 × sin90
2.41sini = 1
i = sin⁻¹(1/2.42)
i = 24.41°.
Since Ia is greater than i (41 > 24.41), the ray will pass through the same medium and makes an angle of 41° (normal).
Therefore, the angle relative to the incoming direction is given by:
θ₁ = 41 + 41
θ₁ = 82°.

Complete Question:
A typical diamond is cut as shown in (Figure 1). A ray of light has entered the flat window at the top of the diamond perpendicular to the surface, as shown in the figure. At what angle relative to the incoming direction is the ray reflected from the first interaction with the surface of the diamond?
Answer:
The answer is A.) Tranquil describes Torres as calm, which is the opposite of how the narrator feels.
Explanation:
Answer: d) the median speed in race a is about 153 miles per hour, and the median speed in race b is about 145 miles per hour.
Explanation:
The whole question is written below:
The box plots show the average speeds, in miles per hour, for the race cars in two different races (figure attached)
. Which statement compares the median speeds for the data in the two box plots?
a) the median speed in race a is about 142 miles per hour, and the median speed in race b is about 140 miles per hour.
b) the median speed in race a is about 120 miles per hour, and the median speed in race b is about 125 miles per hour.
c) the median speed in both races is about 165 miles per hour.
d) the median speed in race a is about 153 miles per hour, and the median speed in race b is about 145 miles per hour.
Firstly, let's explain how to read a box plot (as the shown in the second figure):
- The outer extreme points are the minimum and maximum values, respectively.
- The inner extreme points are the first quartile (also called lower median) and the third quartile (also called upper median).
- The point in the middle is Median.
So, according to this, the median for race a (top plot) is between 150 and 155, and the median for race b (bottom plot) is 145.
Hence, among the given options the correct is:
<h2>
d) the median speed in race a is about 153 miles per hour, and the median speed in race b is about 145 miles per hour.</h2>
