Answer:
λ = 11.29 x 10⁻⁷ m = 1129 nm
Explanation:
According to the law of conservation of energy:
where,
λ = maximum wavelength = ?
h = Plank's Constant = 6.625 x 10⁻³⁴ J.s
c = speed of light = 3 x 10⁸ m/s
e = charge on electron = 1.6 x 10⁻¹⁹ C
V = stopping poteential = 1.1 V
Therefore,
<u>λ = 11.29 x 10⁻⁷ m = 1129 nm</u>
Answer:
Electromagnetic waves travel in a vacuum with a definite and unchanging speed.
When electromagnetic waves travel in vacuum, there is a definite, constant ratio between the magnitudes of the electric and magnetic fields.
Explanation:
Electromagnetic waves are waves that come about due to the vibrations generated between an electric field and a magnetic field. There is presence of oscillating magnetic and electric fields and the two statements mentioned above best describes it's properties.
Answer:
Waves
Explanation:
Subatomic particles are particles that are of the subdivision of an atom and are smaller that atom, they are also described as waves in quantum mechanics.
The initial velocity is obtained as 2.5 m/s.
<h3>What is the initial speed?</h3>
To obtain the initial speed, we have to apply the law of conservation of linear momentum which states that momentum before collision is equal to momentum after collision.
Now, the two fragments initially had one velocity before they were split in two directions opposite each other;
Applying the principle of conservation of linear momentum to this problem;
(2 + 10)v = (6 * 10) - (2 * 15) (they moved in opposite directions)
12v =60 - 30
12v = 30
v = 30/12
v = 2.5 m/s
