What is the smallest separation between two slits that will produce a second-order minimum for 762 nm red light?
ipn [44]

Answer:

1524 nm.

Explanation:

Angular separation of n th minima is given by the expression

Sin θ = n λ / a

Where λ is wavelength of light used and a is separation between two slits .

a = n λ / sin θ

For a to be minimum, sinθ has to be maximum .

maximum value of sin of any angle is 1 .

so the relation becomes as follows

a = n λ

n = 2 , λ = 762 nm.

a = 2 x 762 nm

= 1524 nm.

THE NUMERICAL RATIO OF DISPLACEMENT TO DISTANCE IS:​
Tamiku [17]

There's no general rule.  

Displacement is the length of a straight line from start to finish, and distance is how far you actually traveled from start to finish.

The only thing we really know is that distance can never be shorter than displacement.  So I guess the answer is:

<em>The numerical ratio of displacement to distance is always 1 or less</em>.

(But it has to be written ALL IN CAPITALS.)

How much force is required to hold an empty carton of volume 1.5 L beneath the surface in a sink of water? Assume the carton is
Gwar [14]

Answer:

It will require 14.715 N of force to hold the cartoon beneath the water.

Explanation:

Given the the volume of cartoon is 1.5 liters.

We need to find the force required to hold this cartoon beneath the water.

As we know from the Archimedes principle that the net force is equal to the volume of liquid displaced.

Given volume of the cartoon is 1.5 liters. So, 1.5 liters of water will be displaced.

And we know the density of the water is 1000\ kg/m^3. That is 1\ kg/L

And g=9.81\ m/s^2

F_N=\rho Vg\\F_N=1\times 1.5\times 9.81\\F_N=14.715\ N

So, it will require 14.715 N of force to hold 1.5 liter volume of cartoon beneath the water.
