The frequency of light wave is 0.6*10^15 Hz.
The relation between the speed of light, frequency, and wavelength is given as
c=λν
Plugging the values in the above equation
3*10^8=5*10^(-7)*ν
ν=0.6*10^15 Hz.
Therefore the frequency of the light wave is 0.6*10^15 Hz.
Answer:
If you punched thousands of holes in the aluminum foil, you would see thousands of small images in the viewer.
Explanation:
If thousands of holes is punched/perforated in an aluminum foil, such that there were more holes than foil.
Thousands of small images would be formed, which can be seen in the viewer. Aluminum foil has a good reflective property which allows the thousands of holes punched to reflect equal number of images, although the images are smaller in size than the original image size.
Agriculture would use fresh water
