Coherent light from a sodium-vapor lamp is passed through a filter that blocks everything except for light of a single wavelength. It then falls on two slits separated by 0.420 . In the resulting interference pattern on a screen 2.14 mm away, adjacent bright fringes are separated by 2.90 . What is the wavelength of the light that falls on the slits?

The wavelength of the light that falls on the slit is 5.692 × 10⁻⁴m

Explanation:

Here we have

Fringe separation = 2.90 mm = 0.0029 m

Slit separation = 0.420 mm = 0.00042 m

Distance from slits to screen = 2.14 mm = 0.00214 mm

Wavelength is given by the following relation;

Therefore;

The wavelength of the light that falls on the slit = 5.692 × 10⁻⁴m.

i don't understand. explain it clearly

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
