Pentaprism is a five sided prism with two silvered surfaces giving a non-stop deviation of all rays of light through 90 degress. Used in viewfinders of single-lens reflex cameras
There are multiple devices that emit radio waves. The most obvious is are radiod and microwaves (yes, the food cooker). Wireless applicances also emit radio waves. But don't confuse everything to use microwaves. Some applicances use frequencies instead of radio waves. Some applicances that use frequencies are toy control remotes and a garage door.
I hope this helps! Please make sure ask me if you need more clarity!
