The wavelength of a wave refers to the horizontal distance that is travelled by a wave.
<h3>What is wavelength?</h3>
The wavelength of a wave is given by the formula;
v =λf
f = v/λ
Substituting the values;
f = 3 * 10^8 m/s/410 * 10^-9 m
f = 7.3 * 10^14 Hz
for 2
f = 3 * 10^8 m/s/434 * 10^-9 m
f = 6.9 * 10^14 Hz
for 3
f = 3 * 10^8 m/s/486 * 10^-9 m
f = 6.2 * 10^14 Hz
for 4
f = 3 * 10^8 m/s/657 * 10^-9 m
f = 4.6 * 10^14 Hz

Answer:
A. Solid aluminum oxide and solid iron
Explanation:
The reaction equation is given as:
2Al + Fe₂O₃ → Al₂O₃ + 2Fe
The species on the left hand side are the reactants
Those on the right hand side of the expression are the products.
The products are:
Al₂O₃ and Fe
These are solid aluminum oxide and solid iron
Pretty sure it’s B not 100% tho
Oxidation is basically lose of electron..
hope it helped
Acceleration is defined as velocity per unit time.


Here, a=acceleartion,
v=velocity=36 m/s
t=time=12 s



A car at rest ends accelerates for 12 seconds. After this time the car is going 36 m/s. So acceleration that is a=3 ms⁻².
