Infrared radiation _____. has wavelengths that are shorter than visible light is part of the visible light spectrum has waveleng
ths that are longer than visible light has the same wavelengths as ultraviolet radiation
1 answer:
Answer: has wavelengths that are longer than visible light
Explanation: Electromagnetic spectra comprises of different electromagnetic waves which are arranged in order of increasing wavelengths or decreasing energies.
In order from highest to lowest energy, the waves are arranged as: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves.
E= energy
h= planck's constant
c= velocity of light
= wavelength
As wavelength and energy are inversely related, the wave having higher wavelengths will be lowest in energy. Thus as infrared radiation have lower energy as compared to visible radiation. Thus infrared radiation have higher wavelength as compared to visible radiation.

What you need to know is that the force is
F=ma
The force is the product of mass and acceleration
this means that the acceleration is
a=F/m
a) The force is halved?
this means that f will be
now:
a=
So the accelaration will also he halved (it's the original acceleratation divided by 2)
b) The object's mass is halved?
a=
=a=
which is the original acceleration times two!! so it will double
c) The force and the object's mass are both halved?
now we have
a=
=a=
=a=
so they will cancel each other out and the acceleration will stay the same!
F=ma
