A light bulb produces light with frequency = 4.65 x 1014 Hz. What is the wavelength of light the bulb produces?

6.45 x 10-7 meters

1.55 x 106 meters

6.45 x 1021 meters

1.395 x 1023 meters

6.45 x 10-7 meters

Explanation:

Taking speed of light as 300000000 m/s

We know that speed of light is product of wavelength and frequency and expressed as

s=fw

Where s represent speed, f is frequency and w is wavelength

Substituting 4.65*10^14 Hz for frequency then the wavelngth will be given by

300000000=4.65*10^14 *w

w=300000000÷4.65*10^14

w=6.451612903225*10^-7 m

Rounded off, the wavelength is 6.45 x 10-7 meters
