Question

1) Write the cartesian sign conventio for convex and concave lence.​

Answer 1

Answer:

According to the new Cartesian sign convention for the refraction of light through the concave and convex lens:

According to the new Cartesian sign convention for the refraction of light through the concave and convex lens:All distances are measured from the optical centre of the lens.

According to the new Cartesian sign convention for the refraction of light through the concave and convex lens:All distances are measured from the optical centre of the lens.Distances measured in the direction opposite to the direction of incident light are considered negative.
