The increasing order of photons in terms of energy is Er < Ey < Eb
A photon is a tiny particle of electromagnetic radiation and its energy is proportional to the frequency and rest mass as zero.
By using the formula:
E = h * ν
E = h * c / λ
h = planks constant
c = speed of light
Since h * c is constant
E is inversely proportional to wavelength λ
For blue:
λ = 453 nm
Eb= k / 453
where k is constant
For red:
λ = 660 nm
Er = k / 660
For yellow:
λ = 595 nm
Ey = k / 595
Therefore,
The increasing order of photons in terms of energy is
Er < Ey < Eb.

Rank the following photons in terms of increasing energy: (a) blue (λ = 453 nm); (b) red (λ = 660 nm); (c) yellow (λ = 595 nm).
Answer:
physical: color, appearance chemical: reactivity, flammability
The arrow is between 4.0 and 5.0, so the measurement is at least 4.0. The arrow is between the third and fourth small tick marks, so it’s at least 0.3. We will have to estimate the last place. It looks like about one-third of the way across the space, so let us estimate the hundredths place as 3. The symbol psi stands for “pounds per square inch” and is a unit of pressure, like air in a tire)
He answer is 4.9 the graph to the right really means nothing.
Answer: The molecule
is expected to have a dipole moment of zero.
Explanation:
The product of magnitude of the charge calculated in electrostatic units is called dipole moment.
Formula for dipole moment is as follows.
Dipole moment = Charge (in esu)
distance (in cm)
Non-polar molecules have zero dipole moment.
For example,
is a non-polar molecule so its dipole moment is zero.
is a polar molecule so it will have dipole moment.
is a polar molecule so it will have dipole moment.
has nitrogen atom as more electronegative than hydrogen atom. So, net dipole moment will be in the direction of nitrogen atom.
Thus, we can conclude that the molecule
is expected to have a dipole moment of zero.
