Final answer:
The wavelength of a photon with a frequency of 49.3 THz is approximately 6.09 × 10^-9 m.
Step-by-step explanation:
To find the wavelength of a photon, you can use the formula:
Wavelength = Speed of Light / Frequency
Where the speed of light is approximately 3 × 10^8 m/s. In this case, the frequency is given as 49.3 THz, which is equivalent to 49.3 × 10^12 Hz. Plugging these values into the formula:
Wavelength = (3 × 10^8 m/s) / (49.3 × 10^12 Hz)
Calculating this expression gives us a wavelength of approximately 6.09 × 10^-9 m. Therefore, the correct answer is A) 6.09 × 10^-9 m.
