Answer:
The wavelength of radiation = 8.2 x 10⁻⁵
Explanation:
by the formula
v x λ = C
v = frequency
λ = wavelength
C = speed of light (3 x 10⁸ m/s)
λ = C / v
λ = 3 x 10⁸ / 3.68 x 
λ = 8.2 x 10⁻⁵
the ionic bond would be between the potassium, and hydrogen sulfate.
Answer:
Wavelength of radiation is 0.375×10⁻⁶ m
Explanation:
Given data:
Frequency of radiation = 8.0×10¹⁴ Hz
Wavelength of radiation = ?
Solution:
Frequency and wavelength of lights are inversely proportional to each other.
The wave of light having highest frequency have shortest wavelength and the light with the shortest frequency having highest wavelength.
Formula:
Speed of light = wavelength × frequency
c = λ × f
λ = c/f
This formula shows that both are inversely related to each other.
The speed of light is 3×10⁸ m/s
Frequency is taken in Hz.
It is the number of oscillations, wave of light make in one second.
Wavelength is designated as "λ" and it is the measured in meter. It is the distance between the two crust of two trough.
Now we will put the values in formula.
λ = 3×10⁸ m/s / 8.0×10¹⁴ Hz
λ = 0.375×10⁻⁶ m

Answer: water could be used to wash it since the reaction has ended.
Explanation:
There will be no reaction of water with the Grignard reagent since the reaction has ended, as it is well known that water is a universal solvent for washing of glasswares after experiments but if it is during the reaction it will be more advisable to rinse with alcohol to enhance more accuracy during the experiment
