The wavelength of the emitted photon is(
)= 690nm
<h3>How can we calculate the wavelength of the emitted photon?</h3>
To calculate the wavelength of the photon we are using the formula,
Or,
We are given here,
= The energy difference between the two levels = 1. 8 ev= 
C.
h= Planck constant = 
Js.
c= speed of light = 
m/s.
We have to find the wavelength of the emitted photon = m.
Therefore, we substitute the known parameters in the above equation, we can find that,
Or,
Or,
m
Or,=690 nm.
From the above calculation we can conclude that the wavelength of the emitted photon is 690nm.

Answer:
A hypothesis
Explanation:
A hypothesis is an explanation for those facts and can expierimented on.
I think it’s Malleability
Answer:
Explanation:
Force on a current carrying conductor in a magnetic field is given by the following expression
F = B i L where B is magnetic field perpendicular to wire or current , i is current and L is length of the wire.
Magnetic field of 1.5 x 10⁻⁵ T is making an angle of 60 degree with the wire so the component of field perpendicular to it
B = 1.5 X 10⁻⁵ Cos 30° = 1.3 x 10⁻⁵ T.
Force = BiL
= 1.3 X 10⁻⁵ X .4 X 1
= 5.2 X 10⁻⁶ N.
The direction of force can be found out from Fleming's left hand rule . It will be along downward direction.
