AIEEE 2008 | Geometrical Optics Question 224 | Physics

A student measures the focal length of a convex lens by putting an object pin at a distance $$'u'$$ from the lens and measuring the distance $$'v'$$ of the image pin. The graph between $$'u'$$ and $$'v'$$ plotted by the student should look like

MCQ (Single Correct Answer)

-1

Two lenses of power $$-15$$ $$D$$ and $$+5$$ $$D$$ are in contact with each other. The focal length of the combination is

$$ + 10\,cm$$

$$ - 20\,cm$$

$$ - 10\,cm$$

$$ + 20\,cm$$

MCQ (Single Correct Answer)

-1

The refractive index of a glass is $$1.520$$ for red light and $$1.525$$ for blue light. Let $${D_1}$$ and $${D_2}$$ be angles of minimum deviation for red and blue light respectively in a prism of this glass. Then,

$${D_1} < {D_2}$$

$${D_1} = {D_2}$$

$${D_1}$$ can be less than or greater than $${D_2}$$ depending upon the angle of prism

$${D_1} > {D_2}$$

MCQ (Single Correct Answer)

-1

A fish looking up through the water sees the outside world contained in a circular horizon. If the refractive index of water is $${4 \over 3}$$ and the fish is $$12$$ $$cm$$ below the surface, the radius of this circle in $$cm$$ is

$${{36} \over {\sqrt 7 }}$$

$${36\sqrt 7 }$$

$${4\sqrt 5 }$$

$${36\sqrt 5 }$$
