ludmilkaskok [199]

Answer:

1.28 ×10^-4m

Explanation:

Interference is the superimposition of the wavefront. The superimposition causes bright and dark fringes.

The dark fringe is formed when the additional distance traveled is equal to the multiple wavelength integrals.

From the question, the parameters given are; Wavelength of the light,λ= 600nm, Distance of the screen (D) = 1.44m, order of the bright fringe (m) = 4, Distance of the 4 order fringe (y) = 2.7 cm.

Therefore, for the maximum bright fringe;

dy/D=mλ-----------------------------------------------------------------------------------------------------------------------(1)

Therefore, slotting in equation (1);

d×0.027/1.44=4×600×10^-9

d= 1.28×10^-4 m.

Using the law of conservation of energy, what is the kinetic energy at C? K.E. =
Yanka [14]

Explanation:

It is also important to note that potential energy can be positive, zero or negative. ... Now that the kinetic energy and potential energy have been defined, we can now apply the Law of Conservation of Energy. In other words, the kinetic energy plus the potential energy equals a constant (KE+PE=Constant).
