wavelength and frequency.
the way they reflect.
the orientation of their electric and magnetic fields.
To calculate the frequency of an electromagnetic wave, you need to know the speed of the wave and its
wavelength.
intensity.
refraction.
amplitude.

radar waves.
gamma rays
The full range of frequencies of electromagnetic radiation is called
visible light.
radio waves.
the electromagnetic spectrum.
invisible radiation.
The waves with the longest wavelengths in the electromagnetic spectrum are
Infrared rays.
radio waves
gamma rays
X-rays
The visible light spectrum ranges between
radar waves and X-rays.
television waves and infrared rays.
infrared rays and ultraviolet rays.
ultraviolet rays and gamma rays.
A communications satellite transmits a radio wave at a frequency of 5.0 x 109 Hz. How can you compute for the signal’s wavelength? Assume the wave travels in a vacuum.
(5.0 x 10^9 Hz) x (3.0 x 10^8 m/s)
(5.0 x 10^9 Hz) / (3.0 x 10^8 m/s)
(3.0 x 10^8 m/s) / (5.0 x 10^9 Hz)
(5.0 x 10^9 Hz) + (3.0 x 10^8 m/s)
