What wave on the electromagnetic spectrum has the highest frequency?
Jet001 [13]

Answer:

Explanation:

Answer: Gamma rays

Gamma rays have the highest frequency.

What is an electromagnetic wave?

An electromagnetic wave requires no medium for its propagation.

It consists of a spectrum of different wavelengths.

Different wavelengths of rays have different energies and different frequencies.

Higher frequency rays have the highest energies.

What is gamma-ray?

These are ionized radiations.

Gamma radiations are obtained from the decay of the atomic nucleus.

It has the highest frequency which is why it can penetrate through matter.

It has the smallest wavelength and highest energy.

The frequency of gamma rays is more than 10^19 cycles per second and wavelength less than 100 picometers.

Definition of wave velocity ​
maksim [4K]

Answer:

Velocity = frequency * wave length

Explanation:

Wave velocity is  the measure of how fast the wave is being transmitted to a particular direction.

velocity implies both speed and direction as we know.

The velocity of a wave is equal to the product of its wavelength and frequency

where

  • frequency  - number of oscillations per unit time (measured in Hz)
  • wave length - distance between corresponding points of two consecutive waves  (measured in meters)

How could you increase gravitational force using each factor?
jeka94
The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases.
