Answer : The wavelength of violet light is, 413 nm

Explanation :

Formula used :

\nu=\frac{c}{\lambda}

where,

\nu = frequency of violet light = 7.26\times 10^{14}Hz=7.26\times 10^{14}s^{-1}

As we know that, Hz=s^{-1}

\lambda = wavelength of violet light

c = speed of light = 3.00\times 10^8m/s

Now put all the given values in the above formula, we get:

7.26\times 10^{14}s^{-1}=\frac{3.00\times 10^8m/s}{\lambda}

\lambda=\frac{3.00\times 10^8m/s}{7.26\times 10^{14}s^{-1}}

\lambda=4.13\times 10^{-7}m=4.13\times 10^{-7}\times 10^9nm=413nm

conversion used : 1m=10^9nm

Therefore, the wavelength of violet light is, 413 nm

c=λν

3*10^8 m/s * 10^9 nm/m / 7.26*10^14 s^-1= λ

=413.22 nm

λ=413 nm

What is the covalent bond for Hydrogen + Chlorine (HCI)
kolbaska11 [484]

Answer:

HCl, also known as hydrochloric acid, has a covalent bond. The hydrogen (H) atom shares an electron with the chlorine (Cl) to form the bond.

Explanation:

Consequently, the bonding electrons in hydrogen chloride are shared unequally in a polar covalent bond. The molecule is represented by the conventional Lewis structure, even though the shared electron pair is associated to a larger extent with chlorine than with hydrogen.

Whitepunk [10]

There are five states of matter out of which we encounter three states of matter in our day today life

a) gas b) solid and c) liquid

the main difference between the three is of

a) Inter molecular forces of attraction

b) thermal energy

due to this

a) solid has high intermolecular forces and low thermal energy: thus they have fix shape and occupy fix volume

b) liquid has intermediate forces and medium themal energy. Thus they may have fixed volume and but no fix shape

c) gas has weak intermoelcular forces and high thermal energy. thus they have no fixed volume no fix shape

so in the given problem

the state of the substance D- Gas.

lara31 [8.8K]
Neil Bohr contributed towards science in many ways, but his contributions did not include the charge of an electron. Neil Bohr recognized a relationship between the chemical properties of a substance and the number of valence shell electrons. Moreover, he introduced the atomic model in 1913 and provided the liquid-drop model to explain nuclear fusion.
