We are given:
Wavelength of Green light (λ) = 531 nm OR 531 * 10⁻⁹ m
Speed of light (c) = 3* 10⁸ m/s
<u>Solving for the Frequency of the wave:</u>
We know the relation:
c = νλ
<em>(where ν is the frequency, c is the speed of light and λ is the wavelength)</em>
3*10⁸ = ν*(531*10⁻⁹)
ν = 3*10⁸ / 531*10⁻⁹ [dividing both sides by the wavelength]
ν = 3*10⁸*10⁹ / 531 [ since a⁻¹ = 1/a]
ν = 3*10¹⁷ / 531 [ since mᵃ * mᵇ = mᵃ⁺ᵇ]
ν = 10¹⁷ / 177
ν = 1000 * 10¹⁴ / 177 [we split the numerator to simplify]
ν = 5.65 * 10¹⁴
Hence, the frequency of Green light is 5.65 * 10¹⁴ Hz
Answer:
Acidic inorganic salts, such as AMMONIUM LAURYL SULFATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases.

Answer:
Suspension
Explanation:
This mixture is a simple suspension.
A suspension is a mixture of small insoluble particles of a solid in a liquid or gas. Here, it is insoluble particles in liquid.
- Suspensions are settle on standing this is why they have to be mixed again.
- The particles do not pass through ordinary filter paper.
- They are usually cloudy and have an opaque color.
- The marinade is simply a suspension.
- It is not a solution because they do not settle on standing.
- Also, colloids do not settle on standing.
