A student sets up a double-slit experiment using monochromatic light of wavelength λ. The distance between the slits is equal to 28 λ. (a) Find the angles at which the m = 1, 2, and 3 maxima occur on the viewing screen. m = 1 ° m = 2 ° m = 3 ° (b) At what angles do the first three dark fringes occur? m = 0 ° m = 1 ° m = 2 ° (c) Why are the answers so evenly spaced? Is the spacing even for all orders? Explain.

Select the best definition for wavelength. the height of an oscillating electromagnetic wave the rate at which electromagnetic waves oscillate. the distance between two crests of an electromagnetic wave. the oscillations of electric and magnetic fields select the best definition for frequency. the oscillations of electric and magnetic fields. the height of an oscillating electromagnetic wave. the distance between two crests of an electromagnetic wave. the rate at which electromagnetic waves oscillate

Aheavy boy and a lightweight girl are balanced on a massless seesaw. the boy moves backward, increasing his distance from the pivot point. what happens to the seesaw? it is impossible to predict without knowing additional information. the side the boy is sitting on will tilt downward. the side the girl is sitting on will tilt downward. nothing; the seesaw will remain balanced.

Takumi works in his yard for 45 minutes each saturday. he works in the morning, and he wears sunscreen and a hat each time he works in the yard. what does takumi hope to reduce through his actions? the likelihood of stochastic effects, such as dna mutations the severity of stochastic effects, such as cancer the severity of non-stochastic effects, such as cancer the likelihood of non-stochastic effects, such as radiation sickness
