Two electrons of K-shell can be distinguished by

A

spin quantum number.

B

azimuthal quantum number.

C

principal quantum number

D

magnetic quantum number

Text Solution

Verified by Experts

The correct Answer is:
A
K shell means n = 1 It has only one, Is orbital. Is has four quantum no. as n = Principal quantum number = 1 1 = Angular momentum quantum number = 0 m = Magnetic momentum quantum number = `+1/2,-1/2`

For the same objective, find the ratio of the least separation between two points to be distinguished by a microscope for light of 5000Å and electrons accelerated through 100 V used as the illuminating substance.

An eye can distinguish between two points of an object if they are separated by more than 0.22 mm when the object is placed at 25 cm from the eye. The object is now seen by a compound microscope having a 20 D objective and 10 D eyepiece separated by a distance of 20 cm. The final image is formed at 25 cm from the eye. What is the minimum separation between two points of the object which can now be distinguished?
