1.	Two coherent sources emit light waves which superimpose at a point where these can be expressed as E1=E0sin(ωt+π4) E2=2E0sin(ωt−π4) Here, E1 and E2 are the electric field strengths of the two waves at the given point. If I is the intensity of wave expressed by field strength E1, find the resultant intensity (in I).
Answer» Two coherent sources emit light waves which superimpose at a point where these can be expressed as $E_{1} = E_{0} sin (ω t + \frac{π}{4})$ $E_{2} = 2 E_{0} sin (ω t - \frac{π}{4})$ Here, $E_{1}$ and $E_{2}$ are the electric field strengths of the two waves at the given point. If I is the intensity of wave expressed by field strength $E_{1}$ , find the resultant intensity (in $I$ ).

A horizontal curve with superelevation e = 0.05 (note, e=tanβ ) has a posted speed limit of 60 km/h. For this speed limit, only those vehicles with Y/X ratio(in figure) greater than 2 and travelling at speeds greater than 1.2 times the speed limit, will overturn. However, with recent increase in truck traffic the speed limit needs to be modified such that only those vehicles with Y/X ratio greater than 3 and travelling at more than 1.2 times the speed limit will overturn. What should be the new speed limit?(in km/hr round off to integer) (with respect to the figure, assume that the vehicle is travelling into the plane of the paper).50
