Answer to Problem 4.1CYU
Angular spread for
Explanation of Solution
Given:
Light wavelength,
Order of minimum,
Angular spread
Unit conversion,
Formula used:
Formula for angular separation for minimum condition,
Here D indicates the slit width,
Calculation:
Reduce
Hence, the original slit thickness is
Reduce
Hence, the angular spread at
According to question slit width is increased to a value of
Reduce
Hence, the angular spread at
Reduce
Hence, the angular spread at
Reduce
Hence, the angular spread at
Reduce
As the inverse sine angle cannot be more than 1, thus
Conclusion:
Angular spread for

Rick grows up to be an Earth-bound robotics technician while Mick becomes an intergalactic astronaut. Mick leaves the Earth on his first space mission in the year 2200 and travels, according to his clock, for 10 years at a speed of 0.75c. Unfortunately, at this point in his journey, the structure of his ship undergoes mechanical breakdown and the ship explodes. How old is Rick when his brother dies?arrow_forward
