Explanation: bubbles usually come from soap soooo.... why would they sell it with automobiles?...lol
The figure (examples ) of the question is attached below.
Answer: The answer is prism.
Explanation:
When a ray of white light passes through the prism it separates into many colors or different wavelength of light is seen.
This phenomenon is known as diffraction .In the visible wavelengths of the electromagnetic spectrum, red, is diffracted most and violet is diffracted lowest due to shortest wavelength.
It appears like a rainbow of 7 colors because it is white light that diffracts into 7 colors after passing a prism.
Answer:
mixtures that appear to be the same throughout are homogenous mixtures
Answer:
The initial and final states of the hydrogen atom were n=2 and n=6 respectively.
Explanation:
We must first obtain the energy of the photon;
E= hc/λ
where;
h= Plank's constant = 6.6 * 10^-34 JS
c= speed of light = 3* 10^8 m/s
λ = wavelength of light= 411 nm = 411* 10^-9 m
Substituting values;
E = 6.6 * 10^-34 * 3* 10^8 / 411* 10^-9
E = 4.8 * 10^-19 J or 3.0 eV
But ;
En = 13.6/n^2
So E = En final - En initial
3.0 = -13.6(1/n^2final - 1/n^2initial)
If we substitute n^2final = 6 and n^2 initial = 2 then the RHS becomes approximately equal to the LHS
Therefore the initial and final states of the hydrogen atom were n=2 and n=6 respectively.
