the lense is concave
we know that D=1÷f(m)
then F=1÷D
=1÷-1.5
f=0.66m

Step-by-step explanation:
We know that P = 1/F where focal length is in metre.
Substitute the values and you get
-1.5 = 1/F
F = 1/-1.5
F = -0.66 m
F = -66 cm ( 1 m = 100 cm)
Here the focal length is negative but we know that
Focal length of concave lens is negative
Therefore the lens is Concave ( diverging lens ).
Hope this will help and mark me as brainliest if this helps.
sorry the focal length is 66 cm and not 60 cm
ok
tqqq
i have done the corrections please mark my answer as brainliest.
thanks bhai, kal science 1 ki exam kay liye best of luck.
