Which type of brain waves are seen when a person is concentrating on solving a problem?
Beta waves
What type of reflection is it when light rays reflect in many directions?
It's diffused.
Which type of sample is selected to reflect the demographic characteristics of the population of interest?
Convenience sample
How long does it take RF energy to travel one mile?
The same amount of time as it takes light waves; RF (radio frequency) is a type of electromagnetic wave, just like light. To get the time, divide the distance by the speed (in this case, the speed of light).
What is the standard unit of amplitude?
As radio frequency, in would be modulation in hertz, kilohertz, megahertz. In other areas of measure it could be peak-to-peak. I.E. the maximum absolute value of some quantity that varies, usually with regular frequency. The unit of amplitude depends specifically on the type of wave, certain mechanical waves (e.g. those in in a plucked guitar string) have amplitudes measured in metres. Pressure waves (such as sound) have the unit of pressure as their amplitude (Pascals) where as electromagnetic waves use the electric field strength in volts/metre as the unit of amplitude. As you look at an oscilloscope, the vertical peak of a waveform From Wikipedia: The maximum absolute value of the vertical component of a curve or function, especially one that is periodic.
Is a radio mechanical energy?
No. Radio waves are a type of electromagnetic waves.
Are AM radio waves are an example of longitudinal waves?
No. Radio waves are a type of electromagnetic waves; electroctromagnetic waves are transverse waves.
Are radio waves a type of mechanical wave or a type of electromagnetic wave?
Radio waves are a type of electromagnetic wave.
What do baby monitors have to do with Electromagnetic waves?
The monitoring device is a radio transmitter that sends signals to the radio transmitter. Radio waves are a type of Electromagnetic waves.
What type of waves are found after radio waves and before infrared waves?
Microwaves
What type of wave has the has the lowest frequency?
Radio waves in electromagnetic waves/water waves
Which type of electromagnetic waves is used MOSTLY in communication?
Radio waves.
What type of medium is required by radio waves?
radio waves do not require a medium to travel,it can even travel through vaccum
Which type of waves that carry mobile phones waves?
They are radio waves - in the microwave section of the electromagnetic spectrum.
What type of waves are electromagnet waves?
electromagnetic waves
What type of electromagnetic wave is the lowest?
radio waves
Can radio waves be seen by animals or humans?
No nobody can see any type of waves
