If two light waves were to interfere constructively with each other, you might know this by seeing light that was a. bluer b. redder c. dimmer d. brighter

Charge is distributed along the entire x-axis with uniform density λ. how much work does the electric field of this charge distribution do on an electron that moves along the y-axis from y = a to y = b? (use the following as necessary: a, b, ε0, λ, and q for the charge on an electron.)
