The characteristic impedance of a material is the product of mass density and wave speed, \(Z = \rho c\). One important property is the characteristic impedance of the material. So, due to the partial reflection of light the image is somewhat blurry like in a plane gla. It means some part of the light is reflected back and some part of light passes into the water. What does this statement mean (c) Write all the capital letter of the alphabet which look. Answer: The water surface is transparent therefore the light is partially reflected and partially refracted. The exact behavior of reflection and transmission depends on the material properties on both sides of the boundary. (b) The image in a plane mirror is virtual and laterally inverted. When a wave encounters a boundary which is neither rigid (hard) nor free (soft) but instead somewhere in between, part of the wave is reflected from the boundary and part of the wave is transmitted across the boundary.
