Roshan makes the table below to describe how to draw a ray diagram for a convex lens.
VikaD [51]

Answer:

The ray that goes parallel to the main axis after passing through the lens should also be parallel from the object to the lens

Step-by-step explanation:

To form the image of an object using a convex lens, ray diagrams are used. The following steps are followed when drawing ray diagrams.

1) Light rays are drawn from the object incidented on the lens and parallel to the principal axis. The incident light refracts (bends) through the lens and converges at the focal point at the other side of the lens.

2) Another incident light passes through the optical centre undeflected and intersect with the refracted ray at the other side of the lens.

Based on the above points, Roshan made an error by drawing the ray that goes parallel to the main axis and after passing through the lens made the same ray to be parallel from the object to the lens instead of refracting (bending) after passing through the lens.

Translate by vector (4, -2) and reflect over x axis

translate by vector (4, -2) and reflect over x axis
translate by (4, -2) gives (x-4)^2 - 2
reflect over x axis means * -1 = -(x-4)^3 + 2
