Question

it is of 10th class you can help me by giving photo of answer please help me by solving these two answer i will mark you brainlist if you give me correct answer ​

Answer 1

✍️Question:-

$\rule{300}{1}$

$\red\bigstar$ Distinguished between real and virtual image?

$\blue\bigstar$ Write the rules for sign convention?

✍️Answer:-

1. $\sf {\boxed {\boxed {\tt {\red {Real\:Image}}}}}$

• Light rays actually meet to form a real image.
• Image is inverted.
• Image can be obtained on the screen.
• This image is in front of mirror and behind the lens.
• We can reach to it.
• Example:- Cinema screen.

$\sf {\boxed {\boxed {\tt {\red {Virtual\:Image}}}}}$

• Light do not actually meet to form a virtual image.
• Image is erect.
• Image cannot be obtained on the screen.
• This image is behind the mirror and in front of the lens.
• We can't reach to it..Example:- Our image in plane mirror.

⛄You can write it in distinguished form.

2. $\sf {\boxed {\boxed {\tt {\blue {Rules\: for \: sign\: convention}}}}}$

• The object is always placed to the left of the mirror .This implies that the light from the object falls on the mirror from the left-hand side.
• All distances parallel to the principle axis are measured from the pole of the mirror.
• All the distances measured to the right of the origin [along +x axis] are taken as positive while those measured to the left of the origin[along x axis] are taken as negative.
• Distance measured perpendicular to and above the principle axis [along +y axis] are taken as positive.
• Distance measured perpendicular to the below principle axis [along y axis] are taken as negative.

⛄Finally we finished with our problem
