Answer:
Light travels as a wave. But unlike sound waves or water waves, it does not need any matter or material to carry its energy along. This means that light can travel through a vacuum—a completely airless space. (Sound, on the other hand, must travel through a solid, a liquid, or a gas.)

Answer: nuclear fusion
Explanation: give me a brainliest
There is no scientific evidence to support this claim. And it is not telling what colors are needing to be worn only the stated bright colors which can mean an assortment of things.
Answer:
Explanation:
Person suffering from myopia is unable to see objects beyond 50 cm because far point of his vision is 50 cm . He requires a concave lens
( diverging lens ) to correct his vision .
After using the lens ,
ray of light coming from far off place will appear to be coming from 50 cm after refraction through lens so it will be focused on retina .
object distance u = ∝
image distance v = - 50 cm
focal length f = ?
1 / v - 1 / u = 1 /f
- 1 / 50 - 1 / ∝ = 1 / f
- 1 / 50 = 1 / f
f = - 50 cm
focal length is negative so len is concave.
He requires concave lens of focal length 50 cm .
☁️ Answer ☁️
Violet
Explanation:
1. As the full spectrum of visible light travels through a prism, the wavelengths separate into the colors of the rainbow because each color is a different wavelength. Violet has the shortest wavelength, at around 380 nanometers, and red has the longest wavelength, at around 700 nanometers.
2. Isaac Newton's experiment in 1665 showed that a prism bends visible light andthat each color refracts at a slightly different angle depending on the wavelength of the color.
