Question
**Question:** Which type of electromagnetic radiation has the highest energy?

- ○ Microwaves
- ○ Ultra violet
- ○ Radio waves
- ○ X rays

**Explanation:** 

In this question, students are asked to identify which type of electromagnetic radiation possesses the highest energy. The electromagnetic spectrum is composed of various types of radiation, each with distinct wavelengths and energy levels.

**Options:**

1. **Microwaves:** These have longer wavelengths and lower energy compared to other types of radiation like ultraviolet or X-rays. They are typically used in microwave ovens and for certain types of communication.

2. **Ultra Violet (UV):** This type of radiation has shorter wavelengths than visible light and carries more energy. It is responsible for causing sunburns.

3. **Radio Waves:** These waves have the longest wavelengths and lowest energy in the electromagnetic spectrum, commonly used for broadcasting and communication.

4. **X rays:** With much shorter wavelengths, X-rays possess high energy and are used in medical imaging to view the inside of the body.

The correct answer is **X rays**, as they have the highest energy among the options provided.

**Question:**

For electromagnetic radiation, when wavelength goes UP, energy goes DOWN.

- ○ True
- ○ False

**Explanation:**

This question addresses the inverse relationship between the wavelength and energy of electromagnetic radiation. According to the equation \(E = \frac{hc}{\lambda}\), where \(E\) is energy, \(h\) is Planck's constant, \(c\) is the speed of light, and \(\lambda\) is the wavelength, if the wavelength increases, the energy decreases, and vice versa. This concept is fundamental in understanding the behavior of electromagnetic waves across different spectrums.
