Is there any point to waving the flashlight around when exploring?

Most of the characters have a torch in their hand when you're controlling them. While walking, you can also point that torch in different directions. However, it's a little cumbersome to control, so I'd rather just get on with walking, but I don't want to risk missing out on seeing something important with it.
I'm a few chapters in now, but don't recall ever having shone my torch onto anything important yet. Should I give up waving the torch around and just concentrate on walking about, or is there some benefit to directing the flashlight beam in different directions?
I'm thinking it's possible it may illuminate some clues that I'd otherwise miss, but that's not happened to me yet.

What is your observation as you move the flashlight away from the wall?
The farther away the flashlight is from the wall, the greater area the light will cover. The laser pointer will cover the same area at all distances. The longer the flashlight is left on, the less bright the light will be.Does light travel in waved?
Light travels as waves. Light waves don't always need particles to travel through. They can also travel through outer space or a vacuum. Light waves travel in straight lines.How do you demonstrate diffraction of light?
You can easily demonstrate diffraction using a candle or a small bright flashlight bulb and a slit made with two pencils. The diffraction pattern\u2014the pattern of dark and light created when light bends around an edge or edges\u2014shows that light has wavelike properties.What do you call the bending of light around the corners of objects?
Diffraction, which is defined as the bending of light around the corners of an obstacle or aperture into the region of geometrical shadow of the obstacle, is another significant property of microstructures.Panic! At The Disco - House of Memories (Lyrics)
