If you want to study how energetic waves affect matter, you should study waves with a _______.

1 answer:

4 0

Higher Frequency and shorter wavelength. The energy of light waves increases when there is an increasing frequency and a higher frequency means there are shorter wavelengths. The equation lambda=c/f where lambda is wavelength and f is frequency and c is the speed of the wave.

The circumference of an orbit for a toy on a string is 18 m and the centripetal force is 12 N. Does the centripetal force do any

Snezhnost [94]

Answer:

Work done is 0.

Explanation:

Given that,

The circumference of an orbit for a toy on a string is 18 m, r = 18 m

Centripetal force, F = 12 N

In the circular path, the centripetal force is always perpendicular to the motion of the object. Thus it makes an angle of 90 degrees with the force and displacement. Hence, we can say that the centripetal force does not do any work on the toy when it follows its orbit for one cycle.

A ray of white light moves through the air and strikes the surface of water in a beaker. The index of refraction of the water is

Naily [24]

Answer:

except ii and iii

Explanation:

The angle of reflection is the angle to the normal the white rays strikes the water surface and it is the incidence angle. Since the white light is moving from less dense medium to a denser medium or a medium with a higher refractive index; the angle of refraction will be less than 30 degrees. Total internal reflection cannot occur because the white light is traveling from a less dense medium to a denser medium.
