Calculate the frequency of radiation with a wavelength of 1.27 × 104 °A (angstroms).

Answer in units of s^−1.

I got 8.34080793e-25. Is that right?

DOesn't look right to me.

frequency=speedlight/wavelength
= 3E8/1.27E(-10+4)

Can you elaborate on the steps?

Is the answer 2.362204724e14 Hz?

That looks ok to me (the last figure that is).

are you in whites class?

To calculate the frequency of radiation, you can use the equation:

frequency = speed of light / wavelength

The speed of light is a constant equal to 2.998 × 10^8 meters per second.

First, convert the given wavelength from angstroms to meters. 1 Å (angstrom) is equal to 1 × 10^(-10) meters.

So, the wavelength is 1.27 × 10^4 °A = 1.27 × 10^4 × 1 × 10^(-10) m = 1.27 × 10^(-6) m.

Now you can substitute the values into the equation:

frequency = 2.998 × 10^8 m/s / (1.27 × 10^(-6) m)

By performing the calculation, the frequency of the radiation is approximately 2.36456693 × 10^14 s^(-1).

Therefore, the correct answer is approximately 2.36456693 × 10^14 s^(-1).
