What type of reflection occurs on rough surfaces?Regular reflectionIrregular reflectionParallel reflectionFocused reflectionQuestion 3 of 204. What is a mirror in scientific language?A surface that absorbs lightA surface that reflects light and forms clear imagesA transparent surfaceA rough surfaceQuestion 4 of 205. Why do polished surfaces reflect maximum light?They absorb less lightThey are transparentThey scatter lightThey are roughQuestion 5 of 206. What types of mirrors are mentioned in the document?Plane and spherical mirrorsConcave and convex mirrorsFlat and curved mirrorsTransparent and opaque mirrorsQuestion 6 of 207. Who coated glass with silver to make the first mirror?Justus von LiebigIsaac NewtonAlbert EinsteinThomas EdisonQuestion 7 of 208. What is used to coat the back of a plane mirror?Copper or zincAluminium or silverGold or ironLead or tinQuestion 8 of 209. What substance is applied to make the back of a plane mirror opaque?Lead oxideZinc oxideSilver oxideCopper oxideQuestion 9 of 2010. What kind of image does a plane mirror produce?RealVirtualInvertedDiminishedQuestion 10 of 2011. How does the size of an image in a plane mirror compare to the object?SmallerLargerSame sizeVariableQuestion 11 of 2012. What is the distance of the image from a plane mirror compared to the object?Half the distanceEqual to the distanceDouble the distanceOne-third the distanceQuestion 12 of 2013. Why do we see laterally inverted letters in a plane mirror?Due to light scatteringBecause the image forms behind the mirrorDue to light absorptionBecause of lens effectsQuestion 13 of 2014. What is the minimum height of a plane mirror to see a full image of a person?Full heightHalf the heightTwice the heightOne-quarter the heightQuestion 14 of 2015. What happens when two plane mirrors are at 90 degrees with an object between them?One image is formedNo images are formedMultiple images are formedInverted images are formedQuestion 15 of 2016. What formula determines the number of images formed by two mirrors?n = 360/A - 1n = A/360 - 1n = 360/A + 1n = A/360 + 1Question 16 of 2017.
