A light ray parallel to the x-axis strikes the outer reflecting surface of a sphere at a point (2,2,0). Its center is at the point (0,0,-1). The unit vector along the direction of the reflected is xhat(i)+yhat(j)+zhat(k) Find the value of yz/x^(2) |
Answer» `hat(N)=(2HAT(i)+2hat(j)+hat(K))/3` `hat(e)=-hat(i)` USING `hat(r)=hat(e)-2(hat(e).hat(n))hat(n)` `hat(r)=-hat(i)-(2(-2))/3 ((2hat(i)+2hat(j)+hat(k)))/3=-hat(i)+4/9(2hat(i)+2hat(j)+hat(k))=(-hat(i)+8hat(j)+4hat(k))/9` |
