Read the text and choose the correct answer.When light encounters a smooth surface like a plane mirror, it undergoes ........... (Reflection, Refraction) following the law of reflection where the angle of incidence ............. (equal, bigger) angle of reflection. This phenomenon allows us to understand how light behaves upon striking a mirror surface.In a plane mirror, the image formed is .............(real,virtual) , meaning it appears to be located............. (behind,in front) of the mirror. This virtual image is ............. (upright, inverted) and the.......... (same size,bigger) as the object, maintaining specific characteristics related to mirror reflection.The process of forming an image in a plane mirror involves light rays bouncing off the mirror surface.

An incident ray of light is initially normal to the surface of a plane mirror. The mirror is rotated untilthe angle between the incident and reflected rays is 30°. The mirror has been rotated through an angleof

A ray of light is incidenting normally on a plane mirror. The angle of reflection will beSelect an answerA0°B90°CWill not be reflectedDNone of the above

The light reflected by a plane mirror may form a real imageSelect an answerAIf the rays incident on the mirror are divergingBIf the rays incident on the mirror are convergingCIf the object is placed very close to the mirrorDUnder no circumstances

A light ray strikes a plane mirror at an angle to its surface.  Which of the following is equal to the angle of reflection of the ray?The angle between the surface and the reflected rayThe angle between the incident and reflected raysThe angle between the surface and the normalThe angle between the reflected ray and the normal2A ray of light is normally incident onto a mirror (in other words, it is incident along the normal).  Which of the following statements does NOT apply to this situation?The Law of Reflection will apply when the ray reflects from the surfaceThe normal is at right angles to the surface of the mirrorIts angle of reflection is equal to 90°Its angle of incidence is equal to 0°3Which of the following statements does NOT apply to wavefront diagrams?Wavefront diagrams can be used to describe the reflection of any type of waveIf the speed of a wave is constant and its frequency increases, the distance between its wavefronts will decreaseThe distance between two adjacent wavefronts is equal to the wavelength of the waveWavefronts are always drawn parallel to the direction in which the wave is travelling4A sound wave strikes a flat brick wall.  The angle between the incident wave and the wall is 30°.  What is the angle of reflection of this wave?60°30°150°90°5The angle of incidence of a light ray onto a plane mirror is 20°.  What is the angle of reflection of the ray?70°0°20°40°6A ray of light is travelling from glass into air at an angle of incidence of 40°.  The critical angle for the glass-air boundary is 41°.  What will happen to the ray of light when it strikes the boundary?It will not be refracted or reflected and will continue in its original pathIt will undergo total internal reflectionIt will pass out of the glass and refract away from the normalIt will travel along the boundary (interface) between the air and the glass (in other words, its angle of refraction will be equal to 90°)7A ray of light is travelling from water into air.  The critical angle for the water-air boundary is 49°.  For which of the following angles of incidence will this ray undergo total internal reflection?50°0°49°48°
