What is the energy of a photon corresponding to radio waves of frequency 1.475 106 /s? I got 9.77e-28 as an answer and its wrong so what is wrong with my calculations.
If you are keying this into a computer database, my best guess is that you don't have the right number of significant figures. The 1.475E6 has 4 so you are allowed 4 in your answer. 9.77E-28 has only 3. The unit is joules.
ok thanks for your help
To determine the energy of a photon corresponding to radio waves of a given frequency, you can use the equation:
E = hf
where E is the energy of the photon, h is Planck's constant (approximately 6.626 x 10^-34 J·s), and f is the frequency of the wave.
In this case, the frequency is given as 1.475 x 10^6 /s.
To calculate the energy, you can substitute the values into the equation:
E = (6.626 x 10^-34 J·s) x (1.475 x 10^6 /s)
By multiplying these values together, you should obtain the correct answer for the energy of the photon.
However, if you obtained 9.77 x 10^-28 as your answer, it suggests that there may have been an error in your calculation.
Double-check your calculation to ensure that you have multiplied the values correctly and used proper scientific notation. Pay attention to the units and order of magnitude to avoid errors.
