Answer 1

For the lenses placed coaxially,

For the lenses placed coaxially, We have the relationship P=P

For the lenses placed coaxially, We have the relationship P=P 1

For the lenses placed coaxially, We have the relationship P=P 1

For the lenses placed coaxially, We have the relationship P=P 1 +P

For the lenses placed coaxially, We have the relationship P=P 1 +P 2

For the lenses placed coaxially, We have the relationship P=P 1 +P 2

For the lenses placed coaxially, We have the relationship P=P 1 +P 2 +P

For the lenses placed coaxially, We have the relationship P=P 1 +P 2 +P 3

For the lenses placed coaxially, We have the relationship P=P 1 +P 2 +P 3

For the lenses placed coaxially, We have the relationship P=P 1 +P 2 +P 3 +......

For the lenses placed coaxially, We have the relationship P=P 1 +P 2 +P 3 +...... So,for given case P=P

For the lenses placed coaxially, We have the relationship P=P 1 +P 2 +P 3 +...... So,for given case P=P 1

For the lenses placed coaxially, We have the relationship P=P 1 +P 2 +P 3 +...... So,for given case P=P 1

For the lenses placed coaxially, We have the relationship P=P 1 +P 2 +P 3 +...... So,for given case P=P 1 +P

For the lenses placed coaxially, We have the relationship P=P 1 +P 2 +P 3 +...... So,for given case P=P 1 +P 2

For the lenses placed coaxially, We have the relationship P=P 1 +P 2 +P 3 +...... So,for given case P=P 1 +P 2

For the lenses placed coaxially, We have the relationship P=P 1 +P 2 +P 3 +...... So,for given case P=P 1 +P 2 or P=

For the lenses placed coaxially, We have the relationship P=P 1 +P 2 +P 3 +...... So,for given case P=P 1 +P 2 or P= f

For the lenses placed coaxially, We have the relationship P=P 1 +P 2 +P 3 +...... So,for given case P=P 1 +P 2 or P= f 1

For the lenses placed coaxially, We have the relationship P=P 1 +P 2 +P 3 +...... So,for given case P=P 1 +P 2 or P= f 1

For the lenses placed coaxially, We have the relationship P=P 1 +P 2 +P 3 +...... So,for given case P=P 1 +P 2 or P= f 1

For the lenses placed coaxially, We have the relationship P=P 1 +P 2 +P 3 +...... So,for given case P=P 1 +P 2 or P= f 1 1

For the lenses placed coaxially, We have the relationship P=P 1 +P 2 +P 3 +...... So,for given case P=P 1 +P 2 or P= f 1 1

For the lenses placed coaxially, We have the relationship P=P 1 +P 2 +P 3 +...... So,for given case P=P 1 +P 2 or P= f 1 1 +

For the lenses placed coaxially, We have the relationship P=P 1 +P 2 +P 3 +...... So,for given case P=P 1 +P 2 or P= f 1 1 + f

For the lenses placed coaxially, We have the relationship P=P 1 +P 2 +P 3 +...... So,for given case P=P 1 +P 2 or P= f 1 1 + f 2

For the lenses placed coaxially, We have the relationship P=P 1 +P 2 +P 3 +...... So,for given case P=P 1 +P 2 or P= f 1 1 + f 2

For the lenses placed coaxially, We have the relationship P=P 1 +P 2 +P 3 +...... So,for given case P=P 1 +P 2 or P= f 1 1 + f 2

For the lenses placed coaxially, We have the relationship P=P 1 +P 2 +P 3 +...... So,for given case P=P 1 +P 2 or P= f 1 1 + f 2 1 .
