Answer and Explanation:
Answer : The time taken for the concentration will be, 7.98 seconds
Explanation :
First order reaction : A reaction is said to be of first order if the rate is depend on the concentration of the reactants, that means the rate depends linearly on one reactant concentration.
Expression for rate law for first order kinetics is given by :
where,
k = rate constant =
t = time taken for the process = ?
= initial concentration = 0.860 M
= concentration after time 't' = 0.260 M
Now put all the given values in above equation, we get:
Therefore, the time taken for the concentration will be, 7.98 seconds
They are both electromagnetic waves
Explanation:
Electromagnetic waves are waves consisting of periodic oscillations of electric and magnetic fields. The fields oscillate in a plane perpendicular to the direction of motion the wave, so they are transverse waves.
Electromagnetic waves are the only type of waves able to travel in a vacuum. All electromagnetic waves travel in a vacuum at the same speed, known as the speed of light, equal to:
Electromagnetic waves are divided into 7 different types, depending on their wavelength and frequency. From the shortest to the longest wavelength (and so, from highest to lowest frequency, since frequency is inversely proportional to wavelength), we have:
Gamma rays
X rays
Ultraviolet
Visible light
Infrared radiation
Microwaves
Radio waves
So as we can see, both gamma rays and microwaves are types of electromagnetic waves. The difference between them is their different wavelength/frequency: in fact, the wavelength of gamma rays is extremently short (), while microwaves have longer wavelengths (at the order of the centimeter).
