Answer 2

Hey sista!

Here's your answer!!
_________________

《A》ᴡʜᴀᴛ ɪs ᴘʟᴀɴᴄᴋ's ᴄᴏɴsᴛᴀɴᴛ?

➨The planks constant is one of the most commonly used constants in the quantum mechanics. It is symbolized as h and related the relates the energy in one photon of electromagnetic radiation to the frequency of that radiation.

➨ Planks constant (h) = Energy (E) / Frequency (v) _______Equation 【1】

➨ The Planck's constant is also known as the plank constant.

➨ The 《SI unit》 of planks constant is equal to 6.6261716 × 10^-34 joule-seconds.

➨ And in 《Cgs system》centimeter-gram-second system, we have it's value as 6.626176 × 10^-27 erg-seconds.

_______________

《B》ᴡʀɪᴛᴇ ᴛʜᴇ ᴅɪᴍᴇɴsɪᴏɴᴀʟ ғᴏʀᴍᴜʟᴀ ᴏғ ᴘʟᴀɴᴄᴋ's ᴄᴏɴsᴛᴀɴᴛ.

We know that,

Dimensional formula of energy = M1L2T-2

Dimensional formula of frequency = M0L0T-1

Putting these two values in Equation 【1】, we get.......

The dimensional formula of planck's constant = M1L21 - 1.
_______________

《C》ᴡʜᴀᴛ ᴀʀᴇ ɪᴛ's ᴀᴘᴘʟɪᴄᴀᴛɪᴏɴs ɪɴ ᴘʜʏsɪᴄs?

➨ As I earlier said, plancks's constant is used in quantum mechanics. It is used in number of relations that describe energy, radius and many more properties of an atom in an electron.

➨ It has also been used to solve the Black Body radiation problem and also used by Einstein to describe the photoelectric effect of solar panels.

➨ It is also applied in Heisenberg Uncertainty principle and the Schrodinger Equations. It has generally been used to solve simple problems if physics related to relativity.
