दिया है, सीजियम धातु का कार्य-फलन

W = 2.14 eV

= 214 x 1.6 x 10-19 जूल

आपतित प्रकाश की आवृत्ति

v = 6 x 1014 Hz

प्लांक का नियतांक

h = 6.62 x 10-34 जूल सेकण्ड

∴ आपतित फोटॉन की ऊर्जा

hν= 6.62 x 10-34 x 6 x 1014 जूल

Step-by-step explanation:

Total energy E is defined to be E = γmc2, where m is mass, c is the speed of light,

and v is the velocity of the mass relative to an observer. There are many aspects of the total energy E that we will discuss—among them are how kinetic and potential energies are included in E, and how E is related to relativistic momentum. But first, note that at rest, total energy is not zero. Rather, when v = 0, we have γ = 1, and an object has rest energy.
