Light with a wavelength of 612 nm incident on a double slit produces a second-order maximum at an angle of 25 degree. what is the separation between the slits?

Speration between the slits

Explanation:

Given that,

Wavelength of light,

It is incident on a double slit produces a second-order maximum at an angle of 25 degree.

The condition for maxima is given as :

d = seperation between the slits

m = order, m = 2

d = 0.00000289

or

So, the seperation between the silts is . Hence, this is the required solution.

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
