We can use the formula for the velocity of a wave:
velocity = wavelength x frequency
Since the problem only gives us the wavelength, we need to find the frequency first. We can rearrange the formula for the wavelength of a wave (wavelength = speed of light / frequency) to solve for frequency:
frequency = speed of light / wavelength
The speed of light is approximately 3.00 x 10^8 m/s.
Plugging in the values:
frequency = (3.00 x 10^8) / (1.33 x 10^-35) = 2.26 x 10^42 Hz
Now we can find the velocity:
velocity = (1.33 x 10^-35) x (2.26 x 10^42) = 4.98 m/s
Therefore, the answer is D.
