Question

Microwave ovens operte at 2.45 GHz, Bluetooth electronics and internet routers work at2.4 GHz.Predict which object has the longer wavelength, showing your calculations evidence, to support your prediction .

Answer 1

The object with the longer wavelength is the microwave oven. This can be determined using the equation λ = c/f, where λ is the wavelength, c is the speed of light (3 x 10^8 m/s), and f is the frequency.

For a microwave oven:

λ = (3 x 10^8 m/s) / (2.45 GHz)

λ = 1.22 x 10^-2 m

For a Bluetooth electronic/internet router:

λ = (3 x 10^8 m/s) / (2.4 GHz)

λ = 1.25 x 10^-2 m

Therefore, the microwave oven has a longer wavelength.
