Answer:
Radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all types of electromagnetic radiation. Radio waves have the longest wavelength, and gamma rays have the shortest wavelength.
Answer:
Hi,
It states that the in linear systems, two or more stimuli cause a net stimulus that is equal to the sum of the individual responses. Applying the principle of superposition to waves, two waves of the same magnitude at a point in space add up to form a resultant displacement at that point which equals the sum of the two vectors.
Explanation
When two or more waves meet, they can interact to form a bigger wave or cancel out. In both cases, the resultant effect is caused by a combination of the two. This principle is applied in noise cancelling headphones that capture and cancel the noise around you by playing an opposite sound that ensures the cancelling of the destructive noise.
Best wishes!
Larger than one.
In fact, the index of refraction of a medium is the ratio between the speed of light in vacuum (c) and the speed of light in that medium (v):
![n= \frac{c}{v}](https://tex.z-dn.net/?f=n%3D%20%5Cfrac%7Bc%7D%7Bv%7D%20)
But the maximum speed the light can travel at is exactly c, the speed of light in vacuum: so v is always less (or equal, in case of vacuum) than c, and so n is always greater than 1.
Answer:
The oldest functioning car is La Marquise, a steam-powered, four-wheeled, four-seater vehicle, manufactured by De Dion Bouton et Trépardoux (France) in 1884; three years later it won the world's first automobile race, powering along the 30.5-km (19-mile) track at an average of 42 km/h (26 mph) from Paris to Neuilly, .
