two objects P and q are placed on different positions in front of a Concave mirror and produces image of same size. the size of object p is 3 times the size of object q. consider if object p is placed at 30 cm in front of mirror find the position of object q

f the W3 HTML specifications.
For creating a marquee using CSS, you have to use the CSS animation property together with the @keyframes rule. Let us now see its variations with implementation.
Here you have to implement translateX() for determining the position of the text at the beginning or end of the animation. Your text will then move among these two assigned points as the animation progresses.
<!DOCTYPE html>
<html>
<body>
<style style="text/css">
.marquee {
height: 50px;
overflow: hidden;
position: relative;
background: #fefefe;
color: #333;
border: 1px solid #4a4a4a;
}
.marquee p {
position: absolute;
width: 100%;
height: 100%;
margin: 0;
line-height: 50px;
text-align: center;
-moz-transform: translateX(100%);
-webkit-transform: translateX(100%);
transform: translateX(100%);
-moz-animation: scroll-left 2s linear infinite;
FOLLOW ME -webkit-animation: scroll-left 2s linear infinite;
animation: scroll-left 20s linear infinite;
}
The position of object q = 16.667cm.
Given:
- Two objects P and q are placed on different positions in front of a Concave mirror.
- Focal length = 20 cm.
- Produces image of same size.
- The size of object p is 3 times the size of object q.
- The object p is placed at 50 cm in front of mirror.
To find:
Position of the object q
Explanation:
- In concave mirror,
- The object size will be small - If the object placed in concave mirror after the focal length And up to infinity.
- The object size will be large - when the object come to the focal length.
- From the Given data it shoes that the object must be closer to the mirror to obtain the large size object.
- In front of mirror at a distance of 50cm, the size of object "p" is thrice the time of the size of object "q".
- The resultant image size of q is equal to the image of p, place the object q near to the mirror.
- Hence The object q distance =
= 16.667 cm from mirror.
- Therefore the Position of object q = 16.667cm.
