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.

d) the number of neutrons plus the number of protons

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
