A certain kind of glass has an index of refraction of 1.640 for blue light of wavelength 440 nm and an index of 1.595 for red li

seraphim [82]

Answer: 18.27°

Explanation:

Given

Index of refraction of blue light, n(b) = 1.64

Wavelength of blue light, λ(b) = 440 nm

Index of refraction of red light, n(r) = 1.595

Wavelength of red light, λ(r) = 670 nm

Angle of incident, θ = 30°

Angle of refraction of red light is

θ(r) = sin^-1 [(n(a)* sin θ) / n(r)], where n(a) = index of refraction of air = 1

So that,

θ(r) = sin^-1 [(1 * sin 30) / 1.595]

θ(r) = sin^-1 (0.5 / 1.595)

θ(r) = sin^-1 0.3135

θ(r) = 18.27°

Drag each circle to the correct location on the image. Each circle can be used more than once, but not all circles will be used.

Based on the given information, the type of boundaries these two new plates would share with each other and the Arabian Plate are divergent boundaries.

<h3>Who are geologists?</h3>

A geologist is a scientist who studies the solid, liquid, and gaseous matter that constitutes Earth and other planets.

Geologists have observed that a portion of Africa is breaking away from the main continent. This is happening because the African Plate is in the process of splitting up into two parts. Scientists have named the two new tectonic plates the Nubian Plate and Somalian Plate. Both of these plates are not only moving away from each other but also away from the Arabian Plate.

There are 3 types of boundaries.

At convergent boundaries, the two tectonic plates comes closer to each other.

At divergent boundaries, the plates move away from each other.

At transform boundaries, the plates are moving parallel to their boundary.

Based on this, all boundaries will be divergent boundaries.

A single-wavelength beam of light is pointed at a dark shield with two narrow slits. As a result, an interference pattern forms

lilavasa [31]

Answer:

The slit separation is 2.2μm.

Explanation:

Given that,

Wavelength = 635 nm

Angle = 16.6°

Order number = 1

We need to calculate the slit position

Using formula of slit distance

$d\sin\theta= m\lambda$

$d=\dfrac{m\lambda}{\sin\theta}$

Where, $\lambda$ = wavelength

m = order number

Put the value into the formula

$d=\dfrac{1\times635\times10^{-9}}{\sin 16.6}$

$d=2.2\times10^{-6}\ m$

$d=2.2\ \mu m$

Hence, The slit separation is 2.2μm.

4.Keeping in mind the kinetic energy of a moving vehicle, how can a driver best prepare to enter sharp curves in the roadway?

dsp73

The kinetic energy of the vehicle should be such it balances the centripetal and centrifugal forces whereas coming into and crossing the curve. whereas coming into, the driving force ought to scale back speed by gently persist brakes, till apex purpose has been reached. this can be the nearest purpose of the car to the within of curve line. Once that has been reached, accelerator ought to be gently pressed to use some force to pull the car out of the curve.

Explanation:
He should slowly slow down the speed

The brake is hard as potential in the entry to the curve, then with less force as you start turning. The slowest purpose ought to be at the apex of the curve, once that you're fast once more.

Your tires have a limit to their grip before they slip (skid). the concept is to manage the forces on them. The additional lateral force from the turn there's, the less linear force you'll use braking or fast.

This is why corners are the passing zones on the track. If you'll out-brake the opposite guy going into the flip, you'll be quicker within the turn, however brake too late and you will not be ready to flip while not skidding.
By formula, Kinetic Energy is:
mass of the body time (the speed of the body) everywhere two.

The mass of the body remains constant.
Velocity is variable.
