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.

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
