9. Quantum Mechanics

Even the music we listen to deals with how energy travels to get to our car radio. If an FM Radio station broadcasts its music at 97.7 MHz find the wavelength in angstroms of the radio waves. One angstrom is equal to 10^-10 m.

The distance between the earth and the sun is 1.496 x 10¹⁷ μm. How long (in mins) will it take for light to go from the sun to earth?

When they are burned, certain elements emit light at a specific wavelength. Some wavelengths for certain elements are provided below:

When burned, an unknown element emits light at a frequency of 9.23 x 10¹⁴ s^-1. What is the identity of this unknown element?

An FM radio station found at 103.1 on the FM dial broadcasts at a frequency of 1.031 × 10⁸ s⁻¹ (103.1 MHz). What is the wavelength of these radio waves in meters?

Calculate the wavelength (in nm) of the blue light emitted by a mercury lamp with a frequency of 6.88 × 10¹⁴ Hz.

The wavelength of some red light is 700.5 nm. what is the frequency of this red light?

Calculate the wavelength (in nm) of the red light emitted by a neon sign with a frequency of 4.74 × 10¹⁴ Hz.
