JEE Main 2024 · 31 January · Evening Shift · Physics · Electromagnetic Waves
Given below are two statements: Statement I: Electromagnetic waves...
Given below are two statements:
Statement I: Electromagnetic waves carry energy as they travel through space and this energy is equally shared by the electric and magnetic fields.
Statement II: When electromagnetic waves strike a surface, a pressure is exerted on the surface.
In the light of the above statements, choose the most appropriate answer from the options given below:
Options
- AStatement I is incorrect but Statement II is correct
- BBoth Statement I and Statement II are correct
- CBoth Statement I and Statement II are incorrect
- DStatement I is correct but Statement II is incorrect
Correct answer
B. Both Statement I and Statement II are correct
Step-by-step solution
Electromagnetic wave carries energy shared equally in magnetic and electric field which is given by, , as and .
Also, Electromagnetic wave carries momentum and therefore exerts force when it strikes a surface.
