Answer: It has a range of visible and invisible forms of radiation.
Explanation:
Electromagnetic wave is defined as the wave which is associated with both electrical and magnetic component associated with them. They can travel in vacuum as well and travel with the speed of light i.e 
The electromagnetic radiations consist of radio waves, microwaves, infrared ,Visible , ultraviolet, X rays and gamma rays arranged in order of increasing frequency and decreasing wavelengths.
Only visible light is visible to naked eyes.
The relationship between wavelength and frequency of the wave follows the equation:
where,
= frequency of the wave
c = speed of light
= wavelength of the wave
From the above relation, it is visible that wavelength and frequency follow inverse relation. For increase in wavelength, the value of frequency decreases and vice-versa.
Well it transports white blood cells to infected areas.

In this problem we need to have a centripetal force that is at least as great as the gravitational attraction the object has. The equation for centripetal force is
F = mv^2/r
and the equation for gravitational attraction is
F = ma
Since m is the same in both cases, we can cancel it out and then set the equations equal to each other, so
a = v^2/r
Substitute the known values (radius is diameter/2) and solve for v
9.8 m/s^2 <= v^2/1.5 m
14.7 m^2/s^2 <= v^2
3.834057903 m/s <= v
So the minimum velocity needed is 3.834 m/s.</span>
Sam can study for hours even though it is very loud and there are many possible distractions in the common room, this is an example of a Focus system.
The focus system is a psychological intervention that is purposely designed for use at home or in lecture halls for cognitive or mental assimilation.
When the focus system takes place, an individual is able to further activate the brain networks to engage in more challenging cognitive activities despite the music, distractions, or noise from the background.
From the information given, the ability for Sam to study for hours even though it is very loud was his ability to activate his Focus System.
