Hi everyone
So something strange happened tonight. I've always hung my night lamp on a hook in the wall but last night I kept it on the floor. And i saw fringes form on the floor (see picture)
Could someone please explain why the fringes formed? My guess is that two different waves from two coherent sources must be interfering somewhere but I'm not sure which sources. Is it the wave from the lamp and another reflected from the wall directly behind it? I'm not sure if the wall reflects light so strongly
