Answer:
Explanation:
Check the attachment for the ray diagram
Ray diagrams are important in locating the position of image of an object. It enables us to determine the nature of image formed by an object in from of a mirror or lens.
When drawing ray diagrams to locate the image I of an object O, there are two important steps to follows:
1. Ray emitted from the tip of an object O incidented on the mirror and parallel to the principal axis OP pass towards the focus F of the mirror after reflection.
2. The ray emitting from the tip of the mirror and passing through the centre of curvature of the mirror C undeflected reflects back on the same line of incidence. (Principle of reversibility).
The correct answers are: Options 2,4 and, 5
2)He solved Ptolemy’s model by proving elliptical orbits.
4)He determined that planets move faster when closer to the Sun.
5)He discovered laws of planetary motion.
Answer:
The wavelength of the light is .
Explanation:
Given that,
Distance between the slit centers d= 1.2 mm
Distance between constructive fringes
Distance between fringe and screen D= 5 m
We need to calculate the wavelength
Using formula of width
Put the value into the formula
Hence, The wavelength of the light is .
