The correct Answer is:
To solve the question regarding the speeds of gamma rays, x-rays, and microwaves in vacuum, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Electromagnetic Waves**: - Gamma rays, x-rays, and microwaves are all types of electromagnetic (EM) waves. 2. **Speed of Electromagnetic Waves in Vacuum**: - It is a fundamental principle in physics that all electromagnetic waves travel at the same speed in vacuum. This speed is denoted by the symbol 'c', which is approximately \(3 \times 10^8\) meters per second. 3. **Conclusion**: - Since all electromagnetic waves, including gamma rays (Vg), x-rays (Vx), and microwaves (Vm), travel at the same speed in vacuum, we can conclude that: \[ V_g = V_x = V_m = c \] 4. **Selecting the Correct Option**: - Based on the above reasoning, the correct option would be that all three speeds are equal. ### Final Answer: - The correct option is **D**: \(V_g = V_x = V_m\).
