Light of wavelength 700nm illuminates two slits .0002 m apart. Where will the first order bright spot appear on a screen if the distance from the slit to the first order line is 1.5 m?

explanation:

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

the components of a vector are the parts of the vectors that are to each other.
