Answer: A. Frequency
B. Wavelength
Explanation: Electromagnetic waves are waves which can travel through the vacuum. Electromagnetic waves have electrical and magnetic component associated with them.
Electromagnetic waves are arranged in order of increasing frequencies or decreasing wavelengths.
Radio waves, X-rays, and gamma rays are all electromagnetic waves which have different wavelengths and thus have different frequencies. But they all travel with the speed of light.
The order of frequency of given waves : gamma rays > X rays> Radio waves.
The order of wavelength of given waves : gamma rays < X rays < Radio waves.
Answer:
The answer is D.
Explanation:
The Law of Conservation of mass states that matter is not created nor destroyed in a chemical reaction.
Youre basically allowing the gas to have room to roam free in a large container. When you "squeeze" it into a smaller space, there is less room to move and thus the atoms bounce off of each other more often.
Answer: i wasted one of your answer that sad srry
Explanation:
Answer:
a lens is scattering light
Explanation:
Diagram B shows a plano concave lens. Plano-Concave lenses bend parallel input rays to diverge from one another on the output side of the lens and hence have a negative focal length.
In the given figure, a Plano concave lens is shown. It scatters light. The image is formed in front of lens. The formed image is virtual.
Hence, the correct option is (c) "a lens is scattering light".
