Question

Two lens have ppwer 6D & 4D are in contact what is the power of combination ​

Answer 1

Answer:

Power of combination P= +10D

Explanation:

Hello welcome to Brainly. Please find the below explanation.

Power of first lens P1 = = 6D

Power of second lens P2 =4D

So,

Power of combination of lens

P= P1+P2

P= +6D + 4D

∴ P= + 10 D

Hope, this explanation will help you.

Thanks.

Answer 2

Hey.

Power of an lens means how much the light actually deviates towards that lens.

Now, Power is an scalar Quantity. Thus It can be added subtracted, without any vector Calculations.

Now, when two lens whether of the same nature or of different nature comes close, then the Net Power will be the sum of individual powers.

Since, the given powers is of the convex lens. Now, the Final Power will be the sum of the all powers.

 Final Power = 6D + 4D

  P = 10 D.

Hence, the Final power of the combination is 10 diopter.

Hope it helps.
