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°.

<h3>What is white light?</h3>

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°.

A 400-kg box is lifted vertically upward with constant velocity by means of two cables pulling at 40. 0° on either side of the v

amm1812

Answer:

2558 N.

Explanation:Each rope takes half, so the vertical component of the force on each rope is half of this, or 1960 N.. But they are pulling at a 40 degree angle, so if t is the tension then t*cos(40) = 1960. This gives t = 2558 N.

How do you solve this without using a calculator

My name is Ann [436]

Answer:

A

Explanation:

You must know the basics of Trigonometry to solve this.

First, you must know that

$\frac{3\pi}{4}$

lies in the second quadrant, so sin is negative.

Next, since

pi/4, is the reference angle of 3 pi/4, this means that we can set up a right triangle with pi/4 as an angle, we get

$\cos( \frac{3\pi}{4} ) = \frac{ \sqrt{2} }{2}$

$\sin( \frac{\pi}{4} ) = - \frac{ \sqrt{2} }{2}$

So the answer is A

Select the statements below that are true for the aviation combat element of a MAGTF. Select all that apply.

GaryK [48]

The statements that are true for the aviation combat element of a MAGTF are:

The aviation combat element is usually composed of an aviation unit headquarters and various other aviation units or their detachments.
It can vary in size from a small aviation detachment of specifically required aircraft to one or more Marine aircraft wings.

<h3>What is Aviation?</h3>

This refers to the movement of goods, people, and weapons from one location to another, through aircraft.

Hence, we can see that based on the given description of the functions of the MAGTF, we can see that they are in overall control of the aviation combat elements and they have a unit headquarters and detachments.
