The answer is:
It is virtual and behind the mirror.
Mirrors produce images, either virtual or real.
Virtual images are produced when the image is behind the mirror. Real images are formed when they image is produced in front of the mirror.
So look at the image produced. It's small and found in behind the mirror. This means that it is a virtual image. How do I know that its behind the mirror?
When you look at the diagram, the front side of the mirror is the blue side. This is a convex mirror.
Answer:
BC =980nm
Explanation:
Given wavelength =490nm
m=2
Required to find (OB - OC) = BC (more distant slit - nearest slit ) = dsin theta
We have dsin theta = m*wavelength
or BC = m* wavelength = 2*490nm
= 980nm = 98.000A
The ball was moving for 0.8seconds
This is because 4/5 x 1 = 0.8
Hope this helps and good luckkkk :)
