If the angle of incidence in a plane mirror is 15 degrees, what will be the angle of reflection? QUESTIONS 3.The normal to a mirror line can be described as: A ray of light hits a plane mirror and bounces off of the mirror. the left side of the object becomes the right side of the image and vice-versa. The image formed in a plane mirror is laterally inverted i.e. Image distance is always equal to the object distance in a plane mirror. The image formed by a plane mirror is at the same distance behind the mirror as the object is in front of the mirror i.e. The image in a plane mirror is of the same size as the object. The image formed in a plane mirror is always erect. Such an image cannot be taken on a screen. The image formed in a plane mirror is always virtual. Thus disatnce between object and its image = 2(u-v).(2)įrom equations (1) and (2) distance between image and object isreducedby 2v units in unit time(1 second) Thus distance between mirror and object in unit time = u - v Now if mirroe is approaching you/object with speed v, then distance travelled by mirror in unit time = v units Thus distance between image and object = 2u. Then distance of image = -u (as the image is formed at othersideof the mirror) Solution: Detailed explanation is here: Distance of Image formed in the mirror is same as the distance of the object form thesurfaceof the mirror. A plane mirror is a highly polished plane surface.ĬHARACTERISTICS OF IMAGE FORMED BY PLANE MIRRORS:įollowing are the important characteristics of image formed by plane mirrors.Įx. If the object moves with a velocity 'u' then the image moves with velocity 2u.how? Please do like share comment and subscribe to our channel for more.Any smooth, highly polished reflecting surface is called a mirror. Also for 3-D diagrams to understand children, really clearly.
This is we can even show with the help of other diagrams.
The angle of reflection is the angle formed between the normal and the reflected laser is called angle of deflection in the normal is it is a line drawn perpendicular to the reflective surface at the point of incidence. The definitions of angle of incidence angle of expression and and love Norman is next angle of incidence is nothing but the angle from between the incident Ray and a normal race called the angle of incidence. Okay Lisa to the normal explain You by doing other diagram now, So angle of reflection means this thing is it will be the angle of ignition and you also know the normal is the line drawn perpendicular to the reflecting surface of a point of incidence. And I love interest I have in this thing is going to be the angle of incidence. So this phrase that will be the reflected after bouncing from the given circuit together a picture day. Crazy set to be the pot one is sure to be the initial picture. And what is the reflection during the incident Ray bouncing back in the same medium after the sizing the reflecting surface is called. You can see the definition here Hmm this line which is going to be coming and falling on a wave a be the right set of the incident in this ancient. So this light this is an instant way definition the ray of a light on a Surface a be set to be drinking. So what is the incident dreaming as you can see here the definition of instant Ray incident Ray's the ray of Moonlight on a Surface AP second incident Ray. We are going to see explain the following terms incident Ray lipstick today angle of incidence angle of reflection normal.
