Sound waves can move through various mediums. Similar to the way we can hear a car horn from outside of a house, the sound waves will, however dampened, still pass through mediums, in this case being the wall of a house.
Any type of electromagnetic energy's wavelengths that are shorter than a type of electromagnetic energy's wavelengths is to the left of that type of electromagnetic energy on the diagram. Hence, the wavelength of a type of energy decreases as you progress to the left on the diagram and left of the green light (in the visible spectrum).
M₁ *V₁ = M₂ * V₂
12.0 * V₁ = 6.0 * 500.0
12.0 V₁ = 3000
V₁ = 3000 / 12.0
V₁ = 250 mL
hope this helps!
