In fireworks displays, light of a given wavelength indicates the presence of a particular element. What are the frequency and color of the light associated with each of the following?

The four wavelengths of the problem are not given. Here they are:

a)

b)

c)

d)

The relationship between wavelength and frequency of light wave is

where

f is the frequency

is the speed of light

is the wavelength

For case a), (corresponds to red color), so its frequency is

For case b), (corresponds to blue color), so its frequency is

For case c), (corresponds to red color), so its frequency is

For case d), (corresponds to yellow color), so its frequency is

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
