If "vlf" means "very low frequency" radio, then the speed is
299,792,458 meters (186,282 miles) per second.
The longest waves used regularly for communications are the VLF radio waves with a wavelength up to 30 kilometers.
Radio waves travel at the speed of light, which is the fastest speed possible in a vacuum. Infrared waves also travel at the speed of light, so both types of waves travel at the same speed.
Radio waves travel at the speed of light, which is approximately 300,000 kilometers per second in a vacuum. Infrared waves also travel at the speed of light, so both types of waves travel at the same speed.

Increasing the speed of the plunger will not affect the wavelength of the waves. The wavelength of the waves is determined by the frequency of the source that is creating the waves, not by the speed of the medium through which the waves are traveling.
head into the waves at a slight angle and reduce speed
Electromagnetic waves, such as light and radio waves, have the highest speed in a vacuum, moving at the speed of light, which is approximately 300,000 kilometers per second.
The speed of water waves is determined by the frequency and wavelength of the waves. In deep water, the speed of water waves is proportional to the square root of the wavelength. So, for 6 meter water waves, the speed would depend on the specific conditions of the water body such as depth and type of waves.
Waves will have their highest speed when they are traveling through a medium with the lowest resistance, such as in a vacuum for electromagnetic waves or in a material with high elasticity for mechanical waves. The speed of waves is determined by the properties of the medium they are traveling through, such as density and elasticity.
no.
'Radio' waves are physically and electrically identical to light waves except for their frequency (wavelength), and they travel at the same speed as light does.
The light waves coming from the pencil change speed when they move from air (faster speed) to the glass or water (slower speed). This change in speed causes the light waves to refract or bend.
