To find out the concentration of `SO_(2)` in the air (in parts per million, i.e., ppm), the data was collected for 30 localities in a certain city and is presented below:

Find the mean concentration of `SO_(2)` in the air.

Text Solution

Verified by Experts

The correct Answer is:
`bar(x) = (Sigma F_(i)x_(i))/(Sigmaf_(i)) = (2.90)/30 = 0.99 ` ppm

(a) A point object is placed in front of a double convex lens ( of refractive index n = n_(2) // n_(1) with respect to air ) with its spherical faces of radii of curvature R_(1) and R_(2) . Show the path of rays due to refraction at first and subsequently at the second surface to obtain the formation of the real image of the object. Hence obtain the lens-maker's formula for a thin lens. A double convex lens having both faces of the same radius of curvature has refractive index 1.55. Find out the radius of curvature of the lens required to get the focal length of 20cm.
