Two slits are illuminated by a 348 nm light. the angle between the zeroth-order bright band at the center of the screen and the fourth-order bright band is 13.5 ◦ . if the screen is 154 cm from the double-slit, how far apart is this bright band from the central peak? answer in cm.

0.369 m

Step-by-step explanation:

Given

Distance between slit and screen is

Wavelength

Angle between zeroth order bright fringe and Fourth-order bright fringe is

let distance between the slits be d

Distance of n th bright fringe From central Fringe is given by

Also

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
