Question

The element strontium is often used in fireworks to create a red color. The particular color of red light that strontium emits when heated has a wavelength of 650 nm. 1 What is the frequency of this wave?

Answer 1

The frequency of the red light emitted by strontium is 4.62 x 10^14 Hz.

Step-by-step explanation:

The frequency of a wave can be calculated using the equation:

frequency = speed of light / wavelength

To determine the frequency of the red light emitted by strontium, we need to know the speed of light. The speed of light is approximately 3.00 x 10^8 m/s. Given that the wavelength of the red light from strontium is 650 nm (1 nm = 1 x 10^-9 m), we can substitute these values into the equation to find the frequency:

frequency = (3.00 x 10^8 m/s) / (650 x 10^-9 m) = 4.62 x 10^14 Hz
