Question

Find the energy of each of the photon which
1) corresponds to light of frequency 3×10¹⁵Hz
2) have wavelength of 0.5A°​

Answer 1

Answer:

Megaliths are stone structures. They were used to mark a burial site. A single large stone or several stones could be used to compose a megalith. Some megaliths could be seen above the ground, but some could be underground as well.

The practice of erecting megaliths began around 3000 years ago. This practice was prevalent in the Deccan, the south India, the north-east and Kashmir. Megaliths were probably erected to serve as a signpost. This helped in easily locating the burial site.

Answer 2

1 .by frequency ,energy=hxv

2 .by wavelength, energy=12400/lambda(in angstrom)

Explanation:

answer 1=19.8 x10^-19 joule

answer 2=12400/.5=24800ev
