Question

draw the ray diagram for the concave mirror when the object is between principal focus and pole
is the answer correct??​

Answer 1

With ctrl key and mouse key :-

Go to first cell which you want to select, click mouse pointer and make it an active cell

Press and hold ctrl key on the keyboard

Now click on rest of the cells which you want select without releasing ctrl key and as the required cells are selected release the ctrl key

Note: Don’t click you mouse pointer anywhere else once you release the ctrl key else you will lose all of the highlighted cells

Be careful while selecting cells with using ctrl key, unwanted selection can’t be deselected

In case you release the ctrl key very soon and you wish to select more cells all you need to do is simply press and hold the ctrl key (earlier cells must be highlighted) and start clicking on the additional cells again
