Ray Optics

Ray Optics is a branch of optics that studies the propagation of light in a straight line.
It is also known as geometrical optics.
It deals with the reflection and refraction of light rays.

Analogy between Electrostatics and Magnetism

Electrostatics and Magnetism are two branches of physics that study the behavior of electric and magnetic fields, respectively.
There are many analogies between the two fields.
For example, both fields have charges and poles, respectively, which generate forces and torques.

Root Cause of Magnetism

Magnetism is caused by the motion of electric charges.
This can be due to the spin of electrons in atoms or to the circular motion of electrons around the nucleus.

Magnetising Force or Magnetising Field Intensity

The ability of an external magnetic field to magnetize a substance is called the Magnetising Field Intensity or Magnetising Force.
It is denoted by H.
The unit of H is Ampere per meter (A/m).

Magnetisation or Intensity of Magnetisation

The magnetic dipole moment developed in unit volume is called the Intensity of Magnetisation.
It is denoted by I.
The unit of I is Ampere per meter (A/m).

This quiz covers essential concepts in Ray Optics and the relationships between Electrostatics and Magnetism. It explores the nature of light propagation, reflection, refraction, and the fundamental causes of magnetism. Additionally, it addresses the concept of magnetizing force and its significance in different materials.
