1. The blue color of the sky results from the scattering of sunlight by air molecules. The blue light has a frequency of about 75 M Hz. Calculate the wavelength, in nm, associated with this radiation.

2. Calculate the wavelength of light that has a frequency of 1.5 x 1015 Hz.

3. Light with a frequency of 7.26 x 1014 Hz lies in the violet region of the visible spectrum. What's the wavelength of this frequency of light? Answer in units of nm.

4. What's the wavelength of sound waves having a frequency of 256.0 sec-1 at 20 degress Celsius? Speed of sound = 340.0 m/sec. (The problem is about sound, but this doesn't change the bsic idea of the equation "wavelength x frequency = speed".)

5. A photon has a frequency of 6.0 x 104 Hz. Convert this frequency into wavelength (nm). Does this frequency fall in the visible region?

6. Calculate the frequency of radiation with a wavelength of 442 nm.

7. The wavelength of an argon laser's output is 488.0 nm. Calculate the frequency of this wavelength of electromagnetic radiation.

8. Calculate the frequency of electromagnetic radiation that has a wavelength of 1.315 micrometers.
