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.
