Final answer:
The amount of time it takes for X-rays of frequency 3×10¹8 Hz to travel a certain distance can be calculated using the speed of light. The time to travel 1 mm is approximately 3.33×10^-12 seconds and the time to travel 1 cm is approximately 3.33×10^-11 seconds.
Step-by-step explanation:
The amount of time it takes for X-rays of frequency 3×10¹8 Hz to travel a certain distance can be calculated using the speed of light. The speed of light in a vacuum is approximately 3×10^8 meters per second.
To calculate the time taken to travel 1 mm, we can divide the distance by the speed of light: t = d/c = 0.001/3×10^8 ≈ 3.33×10^-12 seconds.
To calculate the time taken to travel 1 cm, we can use the same formula: t = d/c = 0.01/3×10^8 ≈ 3.33×10^-11 seconds.
