Answer:
Infrared
Visible light
Explanation:
Electromagnetic waves are waves consisting of oscillations of the electric and the magnetic field in a plane perpendicular to the direction of motion of the wave.
Electromagnetic waves travel in a vacuum at the speed of light, which is a constant value:
Also, electromagnetic waves are classified into 7 different types, depending on their wavelength and frequency. From highest to lowest frequency, we have:
gamma-rays
x-rays
ultraviolet
visible
infrared
microwaves
radio waves
Therefore, from the table we see that both infrared and visible light have higher frequency than microwaves, but lower frequency than UV (ultraviolet).
Answer:
1.479 A
Explanation:
Expression for de Broglie wave length
λ =
Where m is mass of neutron ,h is plank constant and KE is kinetic energy of
proton.
Kinetic Energy ( KE) = 3 / 2 kT
=1.5 X 1.38 X 10⁻²³ X 290 = 600.3 X 10⁻²³ J
=
44.777 x 10⁻²⁵
λ =
=1.479 A.
