Refraction and reflection both shows the wave property of light and the difference between them is that during reflection the medium of light will not change while in refraction the light will change its medium
so in reflection of light we use that angle of incidence = angle of reflections with respect to normal
While in refraction we use Snell's law
Diffraction of light is the phenomenon of light in which light will bend at the corners and enter into the region of dark
While absorption is the phenomenon of energy absorption when light incident on any medium or surface
Answer:
i. 0.34
ii. 0.4
iii. 1700 w/m²
iv. 2211.36 w/m²
Explanation:
Given that
Irradiation of the plate, G = 2500 w/m²
Reflected rays, p = 500 w/m²
Emissive power, E = 1200 w/m²

Answer:
Mass is the measure of an object's matter (what it's made up of). The greater an object's mass, the greater its gravitational force. The earth has a strong attracting force for objects with smaller mass (including the moon), and the sun has an attracting force on the earth and other planets in our solar system.
Answer:
A balance
Explanation:
Scientists measure mass with a balance, such as a triple beam balance or electronic balance. In science, the volume of a liquid might be measured with a graduated cylinder.
