The speed of light is 3.0 x 10⁸ m/s. If a microwave has a wavelength of 350 nanometers, what is its frequency?

Sagot :

Answer:

To find the frequency of the microwave, we can use the formula that relates the speed of light to the wavelength and frequency:

Speed of light =Wavelength X Frequency}

Given:

- Speed of light = 3.0 x 10^8 m/s

- Wavelength = 350 nanometers = 350 x 10^-⁹ meters

Let's calculate the frequency using the formula:

Frequency= Speed of light / Wavelength

Frequency= 3.0 × 10^8 / 350 × 10^-⁹

Frequency = 3.0 × 10^8 / 3.5 × 10^-⁷

Frequency= 8.57 × 10^¹⁴ Hz

Therefore, the frequency of the microwave with a wavelength of 350 nanometers is approximately 8.57 × 10^ ¹⁴ Hz.
