Its the most imp chapter in class 12th concerning to the board exam , so, understand in carefully , otherwise u cannot understand wave optics also , and these 2 chap will constitute 40 percent of the phy board paper . 
frst of all read the ncert , in frst reading u will nt understand , but reading is nessasary , 
then for derivation – refer all in one arihant , they hv shrtcut tricks to do derivation . THEORY – NCERT IS MORE THAN ENOUGH , BUT ALL IN ONE ONLY IMP POINTS ARE INCLUDED > 
NUMERICALS – NCERT EXERCISE AND EXEMPLER QUESTION WITH EXAMPLES ARE SUFFICIENT FOR BOARD , u can take examination archieve part of all in one also , they are awesome , 
for jee u need to do h c verma example and question . 
IMP TOPICS TO FOCUS 
1- USES OF OPTICAL FIBRE 
2- CRITICAL ANGLKE CONCEPT 
3- TOTAL INTERNAL REFLECTION , AND ITS USES AND CONDITION ( MOST IMP[) 
3- MIRAGE AND LOOMING 
4- OPTICAL INSTRUMENT DERIVATION ( VVIMP ) 
5-NUMERICALS FROM LATERAL DISPLACEMENT , AND LATERAL SHIFT 
IF U ARE FACING ANY MORE PROB . THEN POST ON FORUM 
ALL THE BEST ..
