Q1. 3cm, 10 cm , J , AEI and CG b) Shift all points to the right by two and half div.
Q2. x = 0.125 m.
Q3. Intensity at the Earth location = 9.25 x 10-26 Wm-2. Power = IS = 2.41 x 10-23 W
Q4.f inversely proportional to wavelength
Q5. Intensity of wave where amplitude is 2A is 4I (4X). Using P = IS , and P'=I'S/2, P' = 2P. But the symbol for P is E . Hence P' = 2E.
