Final answer:
The wavelength of light with a frequency of 6.88×10¸ Hz is 0.435 meters, as calculated using the formula λ = c / f, with c being the speed of light in vacuum.
Step-by-step explanation:
To find out the wavelength of light when its frequency is given, we use the relationship between wavelength (λ), frequency (f), and the speed of light (c), which is expressed by the formula c = fλ. The speed of light is approximately 3.00 × 10¸ m/s in vacuum.
Using the formula, we can rearrange it to solve for the wavelength (λ):
λ = c / f
Plugging in the values, we obtain:
λ = (3.00 × 10¸ m/s) / (6.88×10¸ Hz)
λ = 0.435 meters
Therefore, the correct answer is B) 0.435 meters.
