I perform a simple experiment by shining a torch on a tennis ball in a dark
room. The light was dim and the umbra part of the object was not sharp.I asked
my teacher to confirm if what I observe was correct but she said that the
intensity of light does not affect the the darkness of the umbra formed by an
opaque object. Why is there a contradiction? Please enlighten me. Thank you.
