Question

6) Suggest a piece of equipment satia could use to measure
the angle of incidence and rarefaction-​

Answer 1

Answer:

Measure the angle of incidence - the angle between the normal and incident ray. It is approximately 60 degrees. Now draw the refracted ray at an angle of 34.7 degrees from the normal - see diagram below.

Answer 2

Answer: Balance

Explanation:

For most everyday objects, scientists use a balance to obtain an object's mass. A balance compares an object with a known mass to the object in question. One example of a balance is the triple beam balance.
