Find the wavelength (in nanometers) of a yellow caution
lightwhose frequency is 5.4 x 1014 s-1.

λ = 555.55 nm

Explanation:

the photon energy equation

E = h*f

∴ h = 6.626 E-34 J*sPlanck's constant

∴ f = 5.4 E14 s-1

⇒ E = (6.626 E-34 J*s)(5.4 E14 s-1) = 3.578 E-19 J

∴ E = hc/λ

⇒ λ = hc/E

∴ c ≅ 3.0 E8 m/s

⇒ λ = ((6.626 E-34 J*s)(3.0 E8 m/s))/(3.578 E-19 J)

⇒ λ = (5.555 E-7 m)×(1 E9 nm/m) = 555.55 nm

Atomicity occurs to prevent updates of the database occurring only partially, which can cause greater problems than rejecting the whole series outright.some are monatomic, diatomic, triatomic etc because it shows the number of atoms. for example, monatomic means it contains only one atom.

Matter- occupies space and possesses rest massno matter is the opposite
