A drawing. Short description, A drawing.,Long description, The drawing shows a wave of water moving to the right in a container. As the wave moves, the distance between the peak and trough of the wave gets shorter, but the distance between the peaks of the waves remains the same.
Question
What does the drawing show about the energy of the wave as it moves?
Answer options with 4 options
A.
The energy of the wave increases as shown by the increasing frequency.
B.
The energy of the wave decreases as shown by the decreasing amplitude.
C.
The energy of the wave remains the same as shown by the same wavelength.
D.
The energy of the wave regularly increases and decreases as shown by the peaks and troughs.

the picture is this:

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
