Answer:0.369 m
Step-by-step explanation:
Given
Distance between slit and screen is ![D=154 cm](https://tex.z-dn.net/?f=D%3D154%20cm)
Wavelength ![\lambda =348 nm](https://tex.z-dn.net/?f=%5Clambda%20%3D348%20nm)
Angle between zeroth order bright fringe and Fourth-order bright fringe is ![\theta =13.5^{\circ}](https://tex.z-dn.net/?f=%5Ctheta%20%3D13.5%5E%7B%5Ccirc%7D)
let distance between the slits be d
Distance of n th bright fringe From central Fringe is given by
![y_n=\frac{nD\lambda }{d}](https://tex.z-dn.net/?f=y_n%3D%5Cfrac%7BnD%5Clambda%20%7D%7Bd%7D)
Also ![\tan \theta =\frac{y_4}{D}](https://tex.z-dn.net/?f=%5Ctan%20%5Ctheta%20%3D%5Cfrac%7By_4%7D%7BD%7D)
![y_4=\tan (13.5)\cdot 1.54](https://tex.z-dn.net/?f=y_4%3D%5Ctan%20%2813.5%29%5Ccdot%201.54)
![y_4=0.24\times 1.54](https://tex.z-dn.net/?f=y_4%3D0.24%5Ctimes%201.54)
![y_4=0.369 m](https://tex.z-dn.net/?f=y_4%3D0.369%20m)
3 1/2 cm or 3.5 cm. Because you should divide 280 by 80 which equals 3.5. turn 3.5 to centimeters. Thats your answer.
True. maths is applied in every day life for instance in science and accounting and as well as when daily with money
