Can I mirror my Apple Macbook to an Apple tv 4k 32gb if I buy one?

Hey!

I have a MacBook and a iPhone and an iPad, I want to mirror my screen and videos and photos to the tv but I see on my iPhone and iPad that it says it is looking for an Apple TV. If I buy an Apple TV 32gb 4k will I be able to mirror my Apple MacBook screen and my iPhone and iPad screen to the TV?

Thanks in advance.
