With the ability to measure the motion of land masses, continental drift has become an established fact. The North American and European continents are drifting apart at a rate of about 3 cm per year. At this rate how long (in years) will it take for them to drift 1530 m further apart than at present?
Two isotropic point sources of light (S1 andS2) are separated by a distance d = 250μm along a yaxis and emit in phase at wavelength 841nm and at the sameamplitude. A light detector is located at point P at coordinatexp on the x axis.
