In a double-slit experiment, the slits are illuminated by a monochromatic, coherent light source having a wavelength of 507 nm.

An interference pattern is observed on the screen. The distance between the screen and the double-slit is 1.32 m and the distance between the two slits is 0.112 mm. A light wave propogates from each slit to the screen. What is the path length difference between the distance traveled by the waves for the fifth-order maximum (bright fringe) on the screen

Answer:

The path difference is 2.53 \times 10^{-6} m

Explanation:

Given:

Wavelength of light \lambda = 507 \times 10^{-9} m

Distance between slit and screen D = 1.32 m

Distance between two slit d = 0.112 \times 10^{-3} m

Order of interference n = 5

From the formula of interference of light,

   d\sin \theta = n\lambda

Where d \sin \theta = path difference, n = order of interference

Here we have to find path difference,

 Path difference = 5 \times 507 \times 10^{-9} m

 Path difference = 2.53 \times 10^{-6} m

Therefore, the path difference is 2.53 \times 10^{-6} m

A battery charger is connected to a dead battery and delivers a current of 3.5 a for 4 hours, keeping the voltage across the bat
oksano4ka [1.4K]
The power delivered is equal to the product between the voltage V and the current I:
P=VI=(16 V)(3.5 A)=56 W

This power is delivered for a total time of t=4h=4 \cdot 3600 s = 14400 s, so the total energy delivered to the battery is
E=Pt = (56 W)(14400 s)=806400 J=806.4 kJ

A +2e charge is at the point (-1,0) mm in the x,y plane. A –e charge is at the point (0,1) mm. What is the electric field at the
Gennadij [26K]

Answer:

Let I and j be the unit vector along x and y axis respectively.

Electric field at origin is given by

E= kq1/r1^2 i + kq2/r2^2j

= 9*10^9*1.6*10^-19*/10^-6*(2i+ j)

= (2.88i + 1.44j)*10^-3 N/C

Force on charge= qE= 3*10^-19*1.6*(2.88i +1. 44 j) *10^-3

F= (1.382 i + 0.691 j) *10^-21

 

 Goodluck
