What is a characteristic of both sound waves and electromagnetic waves?
The characteristic of both sound waves and electromagnetic waves are: (2) They transfer energy. Explanation: A wave may be a longitudinal wave whereas, magnetic force waves are transverse waves.
Does a radio wave have mass?
An electromagnetic wave, although it carries no mass, does carry energy. It also has momentum, and can exert pressure (known as radiation pressure).
Does frequency determine color?
Color is determined first by frequency. As the frequency is increased, the perceived color gradually changes from red to orange to yellow to green to blue to violet. The eye doesn’t perceive violet so well. It always seems to look dark compared to other sources at equal intensity.
What is the frequency of different colors?
The visible spectrum
| colour* | wavelength (nm) | frequency (1014 Hz) |
|---|---|---|
| red | 650 | 4.62 |
| orange | 600 | 5.00 |
| yellow | 580 | 5.16 |
| green | 550 | 5.45 |
What two properties of a light wave make color?
The reason that different waves of light appear to be different colors of light is because the color of a light wave depends on its wavelength. For example, the wavelength of blue light is about 450 nanometers, while the wavelength of red light is about 700 nanometers.
What does the frequency of a light wave determine?
The amount of energy in a light wave is proportionally related to its frequency: High frequency light has high energy; low frequency light has low energy. So, gamma rays have the most energy (part of what makes them so dangerous to humans), and radio waves have the least.
How does the frequency of a light wave affect the way it looks?
Wavelength and frequency are inversely related so that longer waves have lower frequencies, and shorter waves have higher frequencies. In the visual system, a light wave’s wavelength is generally associated with color, and its amplitude is associated with brightness.
What happens when you change the frequency of a light wave?
Explanation: Since light travels at the speed of light (wow), if you increase the frequency (number of waves per time frame) then you have to decrease the length of those waves in order to maintain the speed.
How do you find the frequency of a sample?
Divide the wavelength into the velocity to calculate the frequency, expressed as described above as the number of cycles per second, or Hertz – written “Hz.” For example, a water wave with a wavelength of 1 foot traveling at a speed of 4 inches per second has a frequency of 1/3 feet/second divided by 1 foot = . 33 Hz.
