What is the energy (in joules) of an ultraviolet photon with wavelength 150 nm what is its frequency?

We can calculate energy by using Planck's equation that is;

E =  h c / ʎ

where,

h is the Planck’s constant = 6.626 x 10⁻³⁴ m² kg / s

c is the speed of light = 3 x 10₈ m/s

ʎ is the wavelength of light = 150 nm = 150 x 10⁻⁹ m

Now pot the values in equation;

E = (6.626 x10⁻³⁴ m² kg / s) x (3 x 10⁸ m/s) / (150 x 10⁻⁹ m)

E = 1.325 x 10⁻¹⁸ J

Now by using the following equation we can calculate the frequency;

E = hf

f = E/h

f = 1.325 x 10⁻¹⁸ / 6.626 x 10⁻³⁴ 

f = 1.9997 x 10¹⁵ Hz

Ifound this on google “how does an observation of an object differ from an inference about it? observations uses one or more of the senses to gather in formation and record it but an inference is a logical interpretation of the prior knowledge like testing samples.” i hope this you for what your looking for. can you plz mark me brainliest?

Iwould sure like to answer your question but i honestly just don’t know
