What is used for photography in fog? (A) Polaroid (B) Infrared ray (C) Ultraviolet ray (D) X-rays 2. The energy in an electromagnetic wave is: (A) Wholly shared only by electric field vector (B) Wholly shared only by magnetic field vector (C) Equally divided between electric and magnetic field (D) Zero
Understand the Problem
The question consists of two multiple-choice problems related to physics: one about what is used for photography in fog and another about the energy in an electromagnetic wave. The user is likely looking for answers to these questions.
Answer
1. Infrared ray. 2. Equally divided between electric and magnetic fields.
- The answer is Infrared ray (B). 2. The energy in an electromagnetic wave is equally divided between electric and magnetic fields (C).
Answer for screen readers
- The answer is Infrared ray (B). 2. The energy in an electromagnetic wave is equally divided between electric and magnetic fields (C).
More Information
Infrared rays can penetrate fog better than visible light, making them ideal for photography in foggy conditions. The energy distribution in electromagnetic waves is due to Maxwell's equations.
Tips
A common mistake is not considering infrared's ability to penetrate fog. For electromagnetic waves, misunderstandings might arise if the relationship between electric and magnetic fields isn't clear.
