Question
![A light wave has a frequency of \(3.86 \times 10^{14}\) cycles per second.
(a) What is the wavelength?
\[\text{_____} \times 10^{-7} \, \text{m}\]
Explanation: This question asks for the wavelength of a light wave given its frequency. The answer will have the form \(x \times 10^{-7} \, \text{meters}\), where \(x\) is the number to be determined. To find the wavelength, you can use the formula:
\[
\text{Wavelength} (\lambda) = \frac{\text{Speed of Light} (c)}{\text{Frequency} (f)}
\]
where the speed of light \(c\) is approximately \(3.00 \times 10^8 \, \text{m/s}\).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe60d5a34-4bce-47c4-bd59-9c5000e5a1af%2F982a0a08-5f2c-4020-bae2-fd25601d4f8b%2Fi9439f4_processed.jpeg&w=3840&q=75)

Expert Solution
Step 1: FORMULA
wavelength (λ) = speed of light (c) / frequency (f)
The speed of light in a vacuum is approximately 3.00 x 10^8 meters per second (m/s).
