The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept
The question asks for the conversion factor between centimetres and metres.
Step 2: Detailed Explanation
The metric system is based on powers of 10. The prefix "centi-" means one-hundredth (1/100).
This means that 1 centimetre (cm) is 1/100th of a metre.
Therefore, there are 100 centimetres in 1 metre.
\[ 1 \text{ metre} = 100 \text{ centimetres} \]

- The ratio of the power of a light source \( S_1 \) to that of the light source \( S_2 \) is 2. \( S_1 \) is emitting \( 2 \times 10^{15} \) photons per second at 600 nm. If the wavelength of the source \( S_2 \) is 300 nm, then the number of photons per second emitted by \( S_2 \) is \_\_\_\_\_ \( \times 10^{14} \).
