MCQ Chapter 16 General Science Class 8 Maharashtra Board MCQ For All Chapters – General Science Class 8 Reflection of Light 1. What is the most important sense among our five senses according to the document?Sense of hearingSense of visionSense of touchSense of smellQuestion 1 of 202. What happens to objects in a room when the light is switched off at night?They become brighterThey cannot be seenThey change colorThey moveQuestion 2 of 203. What is reflection of light?When light rays pass through an objectWhen light rays fall on an object and change directionWhen light rays are absorbed by an objectWhen light rays bend around an objectQuestion 3 of 204. What are the rays falling on a surface called?Reflected raysNormal raysIncident raysPerpendicular raysQuestion 4 of 205. What is the point at which an incident ray falls called?Point of reflectionPoint of incidencePoint of normalPoint of divergenceQuestion 5 of 206. How many laws of reflection are mentioned in the document?TwoThreeFourFiveQuestion 6 of 207. According to the laws of reflection, what is true about the angle of incidence and reflection?They are unequalThey are equalThey are perpendicularThey are parallelQuestion 7 of 208. In the reflection activity with a comb and torch, what happens to the light rays falling on the mirror?They pass throughThey get absorbedThey get reflectedThey scatter randomlyQuestion 8 of 209. What is the line perpendicular to the mirror at the point of incidence called?Incident rayReflected rayNormalAngle of reflectionQuestion 9 of 2010. What angle does the normal make with the mirror surface? 45° 60° 90° 120°Question 10 of 2011. In the activity with pins and a mirror, what angle of incidence was initially used? 30° 45° 60° 90°Question 11 of 2012. What is the purpose of fixing pins along the incident ray in the reflection activity? To mark the reflected ray To measure the mirror To align the incident ray To block the lightQuestion 12 of 2013. What happens when a light ray is incident perpendicular to the mirror? It reflects at 45° It reflects back along the same path It passes through the mirror It scatters in all directionsQuestion 13 of 2014. What type of reflection occurs from a smooth surface? Irregular reflection Regular reflection Diffuse reflection Random reflectionQuestion 14 of 2015. In regular reflection, how do reflected rays behave? They scatter in different directions They are parallel to each other They converge at one point They disappearQuestion 15 of 2016. What type of reflection occurs from a rough surface? Regular reflection Irregular reflection Parallel reflection Direct reflectionQuestion 16 of 2017. In irregular reflection, why are reflected rays not parallel? Because the surface is smooth Because angles of incidence vary Because light is absorbed Because the mirror is curvedQuestion 17 of 2018. Are the laws of reflection followed in irregular reflection? No Yes Sometimes Only on smooth surfacesQuestion 18 of 2019. How does a barber use mirrors to show the back of your head? With one mirror With two mirrors reflecting each other With a curved mirror With a periscopeQuestion 19 of 2020. What causes the image of the Moon to appear in water? Moonlight emission Reflection of sunlight from the Moon and then water Water glowing Direct light from the SunQuestion 20 of 20 Loading...
