Explanation:
(a)
The relation between frequency and wavelength is shown below as:
c is the speed of light having value 
Given, Wavelength = 505 nm
Also, 1 m = 
nm
So,
Wavelength = 
m
Thus, Frequency is:
(b)
Also, 
Where,
h is Plank's constant having value 
c is the speed of light having value
So,
(c)
Electromagnetic spectrum is range of the frequencies and their respective wavelengths of the various type of the electromagnetic radiation.
In order of the increasing frequency and the photon energy and the decreasing wavelength the spectrum are:
Red , Orange, Yellow, Green, Blue, Indigo, Violet
Increasing wavelength is the opposite trend. Thus, The longest visible wavelength is red and the shortest is violet.
Answer:
Explanation:
Carboxylic acids is a homologous series in which the compounds contain a functional group called the carboxyl group (-COOH). The general molecular formula for carboxylic acids is CnH2n+1COOH. Carboxylic acids contain at least one carboxyl group.
Or in Polish…
Kwasy karboksylowe to homologiczna seria, w której związki zawierają grupę funkcyjną zwaną grupą karboksylową (-COOH). Ogólny wzór cząsteczkowy dla kwasów karboksylowych to CnH2n + 1COOH. Kwasy karboksylowe zawierają co najmniej jedną grupę karboksylową.
Answer:
the color we observe is the wavelength that the object reflects back to us.
Explanation:
light is composed of several wavelengths each wavelengths is a particular color . but for higher wavelengths light becomes invisible. the color we observe is the wavelength of light that the object reflects back to us.
