Determine the frequency of light with a wavelength of 1.247 × 10−7
cm.
answer in units of hz.

Step-by-step explanation:

Light is usually measured by its wavelength or its frequency. Frequency of light is used to represent the number of light waves that passes through a given point per second. Frequency is usually measured in Hertz, Hz.

The formula that relates the frequency of light to it's wavelength is

c = f × lamba

Where c = the speed or velocity of light = 300000000 m/s

Lamba = wavelength

We are given that the wavelength of the light is 1.247 × 10^-7

cm. We will convert 1.247 × 10^-7

cm to meter.

Since 100 centimetres = 1metre

1.247 × 10−7 cm would become

1.247 × 10^-7 /100 = 1.247 × 10^-9m

Frequency of light =speed of light/ wavelength

= 300000000/1.247 × 10^-9

= 240577385725741792 Hz

50x5=$250
