Answer:

Splitting of light in seven different colors showing the complete spectrum is known as dispersion.

Explanation:

The visible part of the complete EM spectrum, visible light, is made up of seven different colors (Acronym: VIBGYOR). When visible light beam is passed through a prism or diffraction grating it splits into 7 different colors, this process is known as dispersion. The band of 7 colors is called as Spectrum of light.

Every element shows a different spectrum. When we study the spectrum of a compound we can get to know which all elements are present inside it. This technique is known as Spectroscopy.

The same technique is used to study the composition of stars. Astronomers study the spectrum of light coming from the stars to know the elements present inside them. Along with that we can also find out the relative motion of stars using the Doppler's effect. We can get to know whether an object is moving towards or away from us by studying its spectrum.

Bats use a process called echolocation to find their food. This involves giving out sound waves that hit possible prey or food.
cupoosta [38]
The type of waves used by bats are sound waves. Most of the species use their larynx to produce ultrasound waves in the frequency range of 20 to 200 kilohertz.
These sound waves are echoed, reflected, by surroundings, in this case food or prey. These reflections are received by the specialized receptor cells in the ears of bats. The reflections are analyzed by the brain to make an image.
Fun fact: The brain cells of bats are also specialized to better analyze the frequency of ultrasound used by the bat.

Does A= 6.4 B=12 C=12.2 Form a RIGHT TRIANLGE?
Lina20 [59]
To answer this question, you must remember the equation:

a²+b²= c²

(6.4)² + (12)²=   (12.2)²

<span>40.96 + 144 = 184.96
</span> (12.2)² = <span>148.84
</span>
184.96 ≠ 148.84

This cannot be a triangle
