It's normally hard to see laser beams moving through the air, so why is it so easy to see the laser beams in the optics demos we do with this laser ray box? #lasers #optics #stem #science #physics #light #shorts

thank you so much for the explanation, that makes sense 🤯 but didn't come to mind at first when watching your videos 😅

Isn’t there a single line thing used by home builders to make sure something is leveled?

Yep! That's another laser line generator just like these

So inside the device Is a lens with a triangle shape? If I understood correctly 😅

@edmundoptics 4 ай бұрын

Actually inside there will be something called a cylinder lens! It spreads light out in one direction but not in the other perpendicular direction, spreading a light beam into a line

@@edmundoptics thanks for your kind answer but then that fills me with so much more doubts. How can a cilinder lens!! proyect a triangle!! Shape to make the gap without light. That's crazy!!

Triangle?

@edmundoptics 4 ай бұрын

Yep, rather than a cylindrical beam of laser light this creates triangles of light expanding away from it

@solaokusanya955 yes we're seeing the bottom of the triangle hitting the table below. Picture a dot starting at the laser that spreads into a longer line as it gets further away from the laser. That is the triangle of light

@@edmundoptics oooooookay!!.. but but.... Why? How did you see all that?... Or is any straightline just tantamount to a triangle just so we could put in "pythagoras?.. are the remaining 2 lines( Opp and Adj) a must to describe any straight line?....
