.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.
1. Each plot represents the meters traveled by both the Hare and the Tortoise over a certain period of time (minutes).
2. The Tortoise lines show it lines is steadily increasing over a period of time. So as more time elapses the faster the tortoise becomes it travels more meters. The Tortoise line shows steady acceleration.
3. The Hare in the first 5 minutes had a rapid fast advancement up to 40 meters. But for the 5-20 mins. period the Hare did not move at all. Its speed stayed at the same place. But towards the end 20-25 mins. marks the Hare started moving again. At the end the Hare at first had a rapid acceleration but stopped for a long time then it sped up briefly.
A constellation is a group of stars.
Since human brains have evolved to look for patterns,
we sometimes seem to see patterns in groups of points.
Different people make different pictures from the patterns ...
it depends on what they have on their mind.
