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°.

Suppose the length of an oarfish is normally distributed with a mean of 6.5 m and a standard deviation of 1.5 m. which group describes 16% of the oarfish population? select each correct answer.
Answer:
Explanation:
oarfish that are shorter than 5 m
Let x be the random variable representing the length of an oarfish. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = standard deviation
The given probability value is 16% = 0.16. From the normal distribution table, the z score corresponding to the probability value is - 0.99
This indicates that the sample mean is lower than the population mean
Therefore,
- 0.99 = (x - 6.5)/1.5
- 0.99 × 1.5 = x - 6.5
- 1.5 = x - 6.5
x = - 1.5 + 6.5
x = 5m
The correct answer is
oarfish that are shorter than 5 m

Which expression represents the volume of the prism? 10x3 cubic units 15x2 cubic units 20x3 cubic units 30x2 cubic units
The expression that represents the volume of the prism is 30x² cubic units.
Option D) is the correct answer.
What is a prism?A prism is simply a solid geometric with two polygonal faces laying in parallel planes and with the other faces parallelograms.
Volume of a prism is expressed as;
Volume = base area × height
Also, the base area is expressed using the area of a trapezoid.
Hence,
Base area = (1/2) × h( a + b )
Now, let;
h = xa = xb = 2xBase area will be;
Base area = (1/2) × h( a + b )
Base area = (1/2) × x( x + 2x )
Base area = (1/2) × 3x²
Base area = 3x²/2
Now volume will be;
Volume = base area × height
Volume = 3x²/2 × h
So, let h be 20 units
Volume = 3x²/2 × 20uniit
Volume = 60x²/2
Volume = 30x² cubic units
Therefore, the expression that represents the volume of the prism is 30x² cubic units.
