The order of increasing energy is red, yellow, and blue
In physics for a given wave function, the wavelength is defined as the distance between two consecutive points in the waveform. Light is considered a wave and a particle. White light can split into colors of different wavelengths.
The wavelength of visible light ranges from 300 to 700 nm comprising the color VIBGYOR. Wavelength is calculated by the formula velocity divided by the frequency.
If the frequency of the given form is high, then the energy is also high.

Rank the following photons in terms of increasing energy: (a) blue (λ = 453 nm); (b) red (λ = 660 nm); (c) yellow (λ = 595 nm).
As the frequency is inversely proportional to the wavelength, the energy is also inversely proportional. A higher wavelength will have lower energy.

Answer:
The molarity of acid is 3 M.
Explanation:
Given data:
Volume of H₃PO₄ = 25 mL
Volume of NaOH = 50 mL
Molarity of NaOH = 1.50 M
Molarity of H₃PO₄ = ?
Solution:
Formula:
M₁V₁ = M₂V₂
M₁ = M₂V₂ / V₁
M₁ = 1.50 M ×50 mL / 25 mL
M₁ = 75 M. mL / 25 mL
M₁ = 3 M
The molarity of acid is 3 M.
