Below is a picture of the different types of electromagnetic radiation Blake is explaining the relationship between the wavelength and the frequency of electromagnetic radiation to his friend
gamma ray
Ultraviolet
Infrared
radio
Xray
microwave

Which of the following would be the correct explanation of this relationship?
If a wave has a long wavelength it will have a low frequency
If a wave has a long wavelength, it will have a high frequency
If a wave has a low quency, it will have an equally low wavelength
All electromagnetic waves have the same frequency, but different wavelength

hi my dude or dudette

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.
