A beautiful girl with two normal eye wants to see full width of her face by a plane mirror. The eye to eye and ear to ear distances of her face are 4 inch and 6 inch respectively. Fine the minimum width of the required mirror.

A beautiful person with two normal eyes wants to see full width of her face by a plane mirror. The eye and ear to ear distances of her face are 10 cm and 14 cm respectively. The minimum width of required mirror is :

A man of height 6 ft wants to see his full image in a plane mirror. The minimum length of the plane mirror required

A man of height 6 ft wants to see his full image in a plane mirror. The minimum length of the plane mirror required

Consider the situation in figure. The bottom of the pot is reflecting plane mirror , S is small fish is a human eye . Refractive index of water is mu . Fish can see two images of human eye , first due to refractive only and other due to refraction and than reflection . Distance of these images from fish are S_(1) "and" S_(2) respectively . Human eye can also see the two images of fish, first due to refraction only and other due to reflection and then refraction . Distance of these images from human eye are S_(3) "and" S_(4) respectively . Match the quantities of column-I (with their value in column-(II) {:("Column I","Column II"),((A) S_(1),(p)H[1 + (1)/(2mu)]),((B)S_(2),(q) H[mu + (1)/(2)]),((C)S_(3) , (r) H[1 + (3)/(2mu)]) , ((D) S_(4) , (s) H[mu + (3)/(2)]):}
