D. Suggested Enrichment/Reinforcement Activitylies Making a Rainbow at Home! A rainbow appears when the light gets split up into its 7 different colours: red, orange, yellow, green ation in Windows blue, indigo and violet. Sometimes referred to as "Roy G. Biv" ; size bondpaper Usually - the reason the light gets split up is because it is passing through a substance that bends the light. The different colored wavelengths bend in different amounts. Red tends to bend the least, so it appears on the top of the rainbow, while violet bends the most and Score ends up on the bottom - with all the other colors in between. When we see a rainbow in the sky, it is usually when the sun is behind us and it is shining through millions of tiny raindrops floating in the sky - all of which are bending the light and projecting the rainbow. Let's start with the easiest! Fill a large bowl or dish halfway with water and prop up a mirror inside il so that part of the minor is under the water and part is out Place the rainbow maker near a sunny window with direct light coming in so that it hits the mirror (early morning or early evening light works best) Play around with holding a large white piece of paper above the maker to "catch" the rainbow. You might have to move a bit until you find it. Play around with moving the paper closer to the mirror and then farther away to see how your rainbow changes! SAFETY NOTE: Just like you should never look directly into the sun, be sure that you do not look directly into the reflection from the mirror, It can damage your eyes. Question: 1.

Power stationsA (1) is an opaque object used to reflect light. Since its surface is smooth (2) reflection takes place. The parts of the mirror are the focus, center of curvature and the (3) which is the distance from the vertex to the the focus of the mirror. ( 4 ) _ mirror has a flat reflective surface while (5) mirrors has curved reflective surface which is either concave or convex, Multiple images are seen in the plane mirror when these mirrors are arranged (6) with each other. The images formed by plane mirror has the same distance, size and height to that of the object. Another effect formed by plane mirror is when the left side of the object appears as the right side of the image and the right side appears as the left. This is known as (7). In curved mirrors the size, type and orientation of the image depends upon the location of the object from the curved mirror. When the object is located far beyond the center of curvature of a concave mirror, the image produced is _(8)_ (9) and (10 ) . When the object is moved between the (11 ) the image produced is virtual, bigger and upright. The images produced using convex mirror are always _(12) (13 ) and (14) No image is produced when the object is located at (15) of the mirror.a Concave mirrors will produce A real, upright images C. real, Inverted images B virtual, inverted images D. no images formed 7 if an object is placed at F In front of a concave mirror, the Image A. forms at F C. forms at 3F B. forms at 2F D. no image forms 8.
