Question

Draw a ray diagram of image formation by a concave mirror when object is placed between focus and centre of curvature

Answer 1

ANSWER :-

$\setlength{\unitlength}{20} \begin{picture}(10,10) \qbezier(7,6)(8,3)(7,1) \put(1,3.5){\line(1,0){6.5}} \put(1,3.5){\line(1,0){6.5}}\put(4.5,3.5){\vector(0,1){1}}\put(4.5,4.5){\vector(1,0){1}}\put(4.5,4.5){\line(1,0){2.9}}\put(4.5,4.5){\line(1, - 1){2.8}}\put(7.4,4.5){\line( - 2, - 1){6.5}}\put(4.5,4.5){\vector(1, - 1){0.7}}\put(4.5,4.5){\vector(1, - 1){2}}\put(7.4,4.5){\vector( - 2, - 1){1}}\put(7.4,4.5){\vector( - 2, - 1){4}}\put(7.3,1.7){\line( - 1,0){5.5}}\put(1.8,3.5){\vector(0, - 1){1.8}}\put(7.3,1.7){\vector( - 1,0){3}}\put(4.4,3.1){ \tt B }\put(3,3.1){ \tt C }\put(1.75,3.75){ \tt B' }\put(1.75,1.2){ \tt A' }\put(5.25,3.1){ \tt F }\put(4.4,4.75){ \tt A }\put(7.5,4.7){ \tt L }\put(7.7,3.25){ \tt P }\put(7.4,1.5){ \tt N }\put(3.125,3.5){\circle*{0.15}}\put(5.4,3.5){\circle*{0.15}}\put(7.1,5.7){\line(1, - 1){0.5}}\put(7.3,4.8){\line(1, - 1){0.5}}\put(7.4,4.1){\line(1, - 1){0.5}}\put(7.1,1.3){\line(1, - 1){0.5}}\put(7.4,2.4){\line(1, - 1){0.5}}\put(7.5,3){\line(1, - 1){0.5}}\end{picture}$

$\implies \displaystyle { \bf \red {{ Nature\: \: }}}= \textsf{ Real inverted} \\ \\ \implies \displaystyle{ \bf \red{{Size}}} \: = \textsf{enlarged(bigger than object)} \\ \\ \implies \displaystyle { \bf \red {{ \: Position\: }}} = \textsf{beyond the c}$

ADDITIONAL INFORMATION :-

➣ centre of curvature :- centre of curvature of spherical mirror is the centre of sphere of which the given mirror is a part .

➣ Principal Axis :- the principal Axis of the spherical mirror is the line joining the pole to the mirror and its centre of curvature .

➣ Focal length :- the distance between the pole and the focus of the mirror is known as the focal length .

➣ Radius of curvature :- the radius of the sphere of the given mirror is a part is known as the radius of curvature of the mirror.

➣ Pole :- this is the mid point of the central point of the section of the sphere used for making the given spherical mirror .

Answer 2

Answer:

Explanation:

When object is placed between the centre of curvature and focus of a concave mirror, the image is formed beyond the centre of curvature, it is real, inverted and larger than the object.

what is ray?✔

• Ray, any of the cartilaginous fishes of the order Batoidei, related to sharks and placed with them in the class Chondrichthyes. The order includes 534 species. Rays are distinguished from sharks by a flattened, disklike body, with the five gill openings and the mouth generally located on the underside.

• A part of a line with a start point but no end point (it goes to infinity)

• ⊥is the symbol for ray

• A portion of a line which starts at a point and goes off in a particular direction to infinity.

❤---------------------------------

• What is an example of a Ray?

• In geometry, a ray is a line with a single endpoint (or point of origin) that extends infinitely in one direction. An example of a ray is a sun ray in space; the sun is the endpoint, and the ray of light continues on indefinitely

• What is called Ray?

• In geometry, a ray can be defined as a part of a line that has a fixed starting point but no end point. It can extend infinitely in one direction. On its way to infinity, a ray may pass through more than one point. ... The vertex of the angles is the starting point of the rays.

❤---------------------------------------------

• What does a number ray show?

• In another branch of mathematics called coordinate geometry, the points that define a ray are located on the plane using their coordinates - two numbers that show where the point is positioned. For more on this, see Ray definition (Coordinate Geometry)

• What is a line with two arrows called?

• We can illustrate that by little arrows on both ends. We can name a line using two points on it. This is line EF or line (note the arrowheads). ... that by drawing an arrow at one end of the ray.

• What is the definition of the point?

• Point. ... A point is an exact position or location on a plane surface. It is important to understand that a point is not a thing, but a place. We indicate the position of a point by placing a dot with a pencil.

• a narrow beam of light, heat, etc. travelling in a straight line from its place of origin:

• A ray of sunshine shone through a gap in the clouds.

• Light rays bend as they pass from air to water.
