Some letters are given which are numbered 1, 2, 3, 4, 5 and 6 followed by four options containing combinations of these numbers. Find the combination of numbers so that letters are arranged accordingly to form a meaningful word.
A6, 2, 3, 5, 4, 1
B5, 4, 1, 6, 2, 3
C3, 4, 1, 6, 5, 2
D1, 6, 5, 4, 3, 2
Read the given statements and select the correct option.
Statement 1 : A concave mirror and a convex lens both have the same focal length in air. When they are submerged in water, they will still have the same focal length.
Statement 2 : The refractive index of water is greater than the refractive index of air.
ABoth statements 1 and 2 are true and statement 2 is the correct explanation of statement 1.
BBoth statements 1 and 2 are true but statement 2 is not the correct explanation of statement 1.
CStatement 1 is true but statement 2 is false.
DStatement 1 is false but statement 2 is true.
When the concave mirror is placed in water, there is a distortion in the light rays passing through it. Hence focal length increases in a concave mirror
