Transcribed Image Text:**Question 3:**
Electromagnetic radiation is used in many forms of communication. Electromagnetic waves with relatively long wavelengths are often used to transmit signals because these waves travel easily around objects. Which type of electromagnetic radiation is best for transmitting signals around objects?
**Options:**
- **A.** Gamma rays
- **B.** Radio waves
- **C.** Ultraviolet rays
- **D.** X-rays
*Explanation:*
The above question pertains to the types of electromagnetic radiation used for communication purposes. One of the crucial factors in determining the effectiveness of electromagnetic waves for signal transmission around objects is the wavelength of the waves. Waves with longer wavelengths tend to be more effective at traveling around objects, making them optimal for communication.
