For which of the following characteristics- speed, wavelength and frequency is light similar to microwaves, and for which does it differ?

My attempt
Light is similar to microwaves for speed and differs for wavelength and frequency. The speed of the waves are the same but the wavelengths of different for different waves and hence the frequency

One should write the mathematical relationship for the speed, frequency and wavelength of light.

Microwaves are a form of electromagnetic radiation, as is visible light, as are radio waves, infrared radiation, ultraviolet light, X-rays and gamma rays.

All EM radiation (photons) travel at the same velocity, the magnitude of which we call the 'speed of light'.

The formula is V = fגּ
V = speed of light and will be constant for all waves so the frequency and wavelength will differ for the different type of waves.

correct. remember, light, microwaves, etc all are EM waves and belong in the EM spectrum
