### NCERT Solutions for Class 12 Physics Chapter 8: Points to Remember

Students can find the important points to remember in Class 12 Physics Chapter 8 below. Noting down the important points helps students quickly revise during the final exam preparation.

• Maxwell found an inconsistency in Ampere’s law and suggested the existence of an additional current, called displacement current.
• An accelerating charge produces electromagnetic waves. An electric charge oscillating harmonically with frequency vv produces electromagnetic waves of the same frequency v.
• Hertz first produced and detected electromagnetic waves with a wavelength of a few metres in the laboratory in 18871887. He thus verified a basic prediction of Maxwell’s equations.
• Electric and magnetic fields oscillate sinusoidally in space and time in an electromagnetic wave. The oscillating electric and magnetic fields, EE and BB, are perpendicular to each other and the electromagnetic wave’s propagation direction.
• In principle, the spectrum of electromagnetic waves stretches over an infinite range of wavelengths. Different names know different regions.
• Infrared waves are also known as heat waves.
