You are a scientist trying to develop a technology that can be used to power wrist watches Which type of electromagnetic wave would be most useful to investigate?
you
How is wavelength important in defining the regions of the electromagnetic spectrum?
All waves of the electromagnetic spectrum have the same speeds but different frequencies and wavelengths. So, wavelength is important for defining the regions in the electromagnetic spectrum (frequency would have been equally useful)
What would held you float safely to the ground from an airplane?
A parachute would help you float safely to the ground from an airplane.
Photon does not have charge then how does it have electromagnetic field?
Well one way to look at it is that a photon IS an electromagnetic field. The photon is the gauge particle for the electromagnetic force. Without photons there would be no electromagnetic interaction force, and therefore no electromagnetic fields.
Is The range of different electromagnetic waves is called the electromagnetic span?
You could certainly call it that if you like, but most people wouldn't know what you mean. Many of them would understand you better if you called it the "electromagnetic spectrum", (while the rest would still be lost).
Where would you find an electromagnet in a vacuum cleaner?
The motor in a vacuum cleaner is an electromagnetic device.
Which device would be most useful for looking at the Moon?
A telescope would give you a detailed view.

For what kind of construction jobs would it be beneficial to have a laser measuring device?
A laser measuring device is useful in most any construction job as it is a very accurate tool. It is useful for remodeling jobs as well as upgrades in homes.
Which device would be most useful for measuring radiation in a nuclear laboratory?
A dose meter or perhaps a Geiger counter.
How is wavelength important in defining the regions of the electromagnetic spectrum?
All waves of the electromagnetic spectrum have the same speeds but different frequencies and wavelengths. So, wavelength is important for defining the regions in the electromagnetic spectrum (frequency would have been equally useful)
Can you use a 220v outlet to plug a 110v electronic device into?
You cannot directly plug a 110v device into a 220v outlet. This can cause damage to the device or even create a safety hazard. You would need a voltage converter or transformer to safely convert the 220v outlet to the appropriate voltage for the 110v device.
What do you call energy transferred as an electromagnetic wave?
I would call it an electromagnetic wave, or electromagnetic energy.
What is the significance of operating point in transistor?
Basically, a Q-point of any device gives information about the operating current & voltage of that particular device..This would help us to know about the max. & min. current or voltage upto which the can be operated safely.
All of the frequencies or wavelengths of electromagnetic radiation make up the electromagnetic?
I would imagine that they would - by definition!
What things can be used to detect invisible forms of electromagnetic radiation?
Different devices are used to detect different frequency ranges of electromagnetic waves. You simply can't use the same device to detect x-rays, than you would use to detect radio waves, for example.
Are the sun's rays mechanical waves or electromagnetic waves?
Electromagnetic waves
