Ultraviolet, visible, infrared, and radio waves are passing the atmosphere. O<span>ur atmosphere blocks most ultraviolet light (UV) and all X-rays and gamma-rays from reaching the surface of Earth. With this in mind B: is your only answer.</span>
Answer:
at n= 3 λ = 656 nm
at n= 2 λ = 121.58 nm
Explanation:
Given details
transition of hydrogen atom from n = 2 to n = 3 state
Difference in energy between n = 3 state and n = 2 state :
so, energy of photon is given as
So solve for wavelength
so, λ
=
= 656 nm
for second transition,
energy transmitted is given asΔE
and it is calculated as
E = 1.635*10-18 J solving for wavelength in ENERGY equation we get
so, m
= 121.58 nm
Answer:
a. 3.039cm
b.magnetic field is
Explanation:
Direction of the solenoid magnetic field is along the axis of the solenoid. and magnetic field due to the wire perpendicular to that due to the solenoid.. Magnetic field at r is given by:
Angle of net magnetic field from axial direction is given by:
,
Field due to solenoid:
Field due to wire:
Therefore, r:
Hence, the radial distance is 3.039cm
b.The magnetic field strength is given by:
Hence, the magnetic field is
