in olden days kings used to burn the enemies ships and their camp tents using mirrors at the time of battles
a. imagining what type of mirrors they have used?
b. What kind of energy they used in defecting enemies?
c. To destroy the enemies what kind of method they have applied?
d. Explain this with a ray diagram?
Answers
Answer:
d) sorry not able to give it ....but I will explain it and u can draw it nicely by yourself..
Explanation:
a) they used concave mirrors which are also known as converging mirrors .
b) solar energy.
c) they used the technique of light intensity. As the sun is tooooo big , the light rays of it in a small space r almost parallel to each other . So we know when the light rays fall on the concave mirror parallel to the principal axis, they all converge at the focus . The point where they converge is a point of high intensity of light and high intensity = high temperature.
This high temperature used to burn their camps !!
hope it helped.
Answer :
a. Concave mirror
b. Solar energy
c. Light intensity
Explanation :
a. With the use of a concave mirror, kings used to destroy enemy ships and tents in ancient times. Concave mirrors are convergent mirrors, which means that when parallel sun light rays strike the surface of a concave mirror, all of the rays converge at a single point after reflection.
b. With the use of solar energy, rulers used to destroy enemy ships and tents in ancient times. Concave mirrors are convergent mirrors, which means that when parallel sun light rays strike the surface of a concave mirror, all of the rays converge at a single point after reflection.
c. They applied the light intensity technique. Sunlight is so intense that its light rays in a tiny space are nearly parallel to each other. As a result, we know that when light rays fall parallel to the major axis on the concave mirror, they all converge at the focus.
d. Refer below diagram.
