This is deliberately done so that the driver in a vehicle ahead can easily spot the ambulance and can give way. The word ‘AMBULANCE’ is written in laterally inverted form on the front of the ambulance. This is the reason, your right hand looks like the left hand of your image. Lateral Inversion in Plane Mirror: A plane mirror makes laterally inverted image. The distance of image and object from the plane mirror is same. Image formation in Plane Mirror: Image is of the same size as object. Virtual image is formed behind the mirror. Virtual Image: When the image cannot be obtained on a screen, it is called virtual image. Images formed on the film of a camera are real images. Images formed on the retina are real images. Real Image: When the image can be obtained on a screen, it is called real image. Whenever an image is formed by a mirror or by any reflecting surface the laws of reflection are obeyed. Angle of incident and angle of reflection are equal.The incident ray, the reflected ray and the normal at the point of incidence lie in the same plane.We are able to see images in mirrors or in water, because of reflection. Reflection: When light falls on a shiny surface, it bounces back. In case of a bent tube, the flame cannot be seen.Ĭhapter List Plant Nutrition Animal Nutrition Fibre to Fabric Heat Acid Base Salt Changes Weather Climate Wind Storms Soil Respiration Circulatory System Plant Reproduction Motion Time Electric Current Light Water Forest Wastewater When the candle is viewed through a straight tube, its flame can be seen. The following experiment proves that light always travels in a straight line. You cannot see an object in complete darkness because there is not light to bounce back from the object. We are able to see the world around us because of light.
