When the the beaker with the coin was empty, the coin appeared to be regular in size. Once we added water to the beaker, we observed that the coin looked enlarged from the sides. Meanwhile the the coin looked regular from the top and bottom.

We also conducted another experiment and put a silver watch into the beaker, and found that when it is kept straight that the dial acts like a mirror.

In our experiment we planted 2 nails in the incident ray away from the glass slab the nail appears bigger and the directions we see it changes

Observation :the spoon looks enlarged and bent

In this activity we learned about refraction of light. We drew a line on a paper and we placed a glass slab right in front of it , the. We put pins on the line.Observation:Now when we looked through the glass slab we say that the pin was on another line.Later when we drew the other line we saw that the two lines don't coincide.

Activity 1:
Observation
Q.1 We observe that the pencil when immersed in water looks biggerand  it looks like it's bent
Q.2 no,it looks like it is bending because light passes through the water it deflects In a different way due to its variation in density

We were given the activity of glass observation.
This is our observation:
The image (nail) formed is a bit enlarged than the normal and usual size.
If a ray of light is travelling from air to glass. The light will bend.
