.Answer:
491.4 nm
Explanation:
The distance between central and first maxima is,
And the distance between screen abnd grating is,
Now the angle can be find as,
Now the grating distance is,
Now with m=1 condition will become,
So,
Therefore the wavelength of laser light is 491.4 nm.
Answer:
Yellow light is a combination of red and green light. So combining blue with yellow light is like combining blue light with red and green light. The result of combining these three primary colors of light is to produce white light.
A graduated cylinder measures volume. This helps find density because:
Density = Mass / Volume
