Answers

In the long run, diseconomies of scale will exist as the inputs are raised by 10 percent and the output by 5 percent.

What are diseconomies of scale?

Diseconomy is the disadvantage of the financial and the economical sector of the long-run businesses that arise when the input and the cost of production are increased.

The input and the output are dependent on each other and the cost of production determines the financial gain or loss in a business. So, if the input and the output both are increasing then it will lead to diseconomy.

A beam of white light goes from air into the water droplet at an incidence angle of 36.2 degrees. what is the angle between the red (660 nm) and violet (410 nm) parts of the refracted light?

Answers

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°.
