Calculate the frequency of radiation with a wavelength of 1.27 × 10^4 °A (angstroms).?
Calculate the frequency of radiation with a
wavelength of 1.27 × 10^4 °A (angstroms).
answer in units of s^-1 (hertz)
i got 2.36*10^14 and it was wrong.
plz do not use scientific notation in your answer.

Given:
Speed of light c = 299792458 m/s.
Wavelength λ = 1.27×10^4 angstroms = 1.27 × 10^−6 meters
= 0.00000127 m.
Solution:
Frequency f = c / λ = 299792458 / 1.27×10^−6 = 236057053543307 Hz
= 2.36×10^14 Hz.
Don't know, why this should be wrong.
Cheers ebs
PS: Sometimes the unit Ångström (angstrom) = 10^−10 m = 0.1 nm is used for wavelength.
Frequency is the inverse of the wavelength, and vice versa. A Hertz is the unit of frequency, and it potential a revolution of a million in line with 2d. subsequently, 10 Hertz potential the wave has ten wavelengths in line with 2d. in case you calculate how far it traveled in one 2d, and divide that by the frequency, you will get the wavelength. additionally, electromagnetic radiation propagates on the fee of sunshine, extra or less 3*10^8 m/s. notice: this could provide your answer in meters.
