Answer:
A) An interference pattern
Explanation:
the two slit experiment is key to understand the microscopic world. The wave-like properties of light were demonstrated by the famous experiment first performed by Thomas Young in the early nineteenth century. In original experiment, a point source of light illuminates two narrow adjacent slits in a screen, and the image of the light that passes through the slits is observed on a second screen.
<u>Key Points</u>
- waves can interfere, for light this will make a series of light and dark bands
- matter particles, such as electrons, also produce interference patterns due to their wave-like nature
- so with a high flux of either photons or electrons, the characteristic interference pattern is visible
Answer:the frequency decreases and the wavelength increases
Explanation:
The frequency decreases and the wavelength increases
Answer:
time required to mow lawn is 1274.06 minutes
Explanation:
given data
average mow = 1400 square meters each hour
area = 320000 square feet
to find out
How many minutes will take to mow lawn
solution
we know that here 1 square feet is equal to 0.092903 square meter
so 320000 square feet will be = 0.09203 × 320000 = 29728.9728 square meter
so time required is express as
time required =
time required =
time required = 21.23 hours
so time required = 21.23 × 60 min = 1274.06
time required to mow lawn is 1274.06 minutes
