What is the wavelength of a photon having a frequency of 87.9 THz?

Answer 1

635 nm

Answer 2

c = wavelength X freqency

therefore (299,792,458 m/s) equals (wavelength) times (87,900,000,000,000 s[-1])

therefore wavelength = 299,702,458 m/s divided by 87,900,000,000,000 s[-1]

= 3.40958 x 10[-6] m

= 3.40958 x 10[-3] mm

= 0.00340958 millimeters

Answer 3

Velocity equals frequency times wavelength (v=fλ). The velocity is equal to the speed of light (3 x 10^8). Rearranging the equation gives f=v/λ. Therefore f = (3 x 10^8)/(788 x 10^-9). f = 3.81 x 10^14 Hz.

Answer 4

The wavelength of a photon can be determined using the formula λ = c / f, where λ is wavelength, c is the speed of light (approximately 3.00 x 10^8 m/s), and f is frequency. Substituting in the values gives λ = (3.00 x 10^8 m/s) / (87.9 x 10^12 Hz) ≈ 3.42 x 10^-6 meters = 3.42 micrometers.
