Final answer:
The wavelength of microwaves with a frequency of 2.45x 10^9 HZ is found using the equation for the relationship between speed of light, wavelength and frequency. The approximated wavelength is 12.2 cm.
Step-by-step explanation:
To find the wavelength of microwaves if the frequency is 2.45x 10^9 HZ, first, you need to understand the relationship between frequency, wavelength and the speed of light. This relationship is described by the equation: speed of light = wavelength * frequency.
The speed of light (c) is a constant and equal to approximately 3.00 x 10^8 meters per second. Given the frequency (f) of 2.45x 10^9 HZ, we can solve for the wavelength (λ) by rearranging the equation to: wavelength = speed of light / frequency.
Substituting the values into the equation gives us: wavelength = 3.00 x 10^8 m/s / 2.45x 10^9 HZ = 0.122 m or 12.2 cm. Therefore, the wavelength of microwaves with a frequency of 2.45x 10^9 HZ is approximately 12.2 cm.
