Answer:
D. 0.60 um
Explanation:
Given the following data;
Frequency = 5.0x10^14 Hz
Speed = 3 x 10^8 m/s
To find the wavelength;
Wavelength = speed/frequency
Substituting into the equation, we have
Wavelength = 3 x 10^8/5.0x10^14
Wavelength = 6 × 10^7m
But 1 meter (m) = 1000000 micrometer (um)
6 × 10^7 meter = 0.6 micrometer.
