Coherent light rays of wavelength λ strike a pair of slits separated by distance d at an angle θ1 with respect to the normal to the plane containing the slits as shown in Figure P36.9. The rays leaving the slits make an angle θ2 with respect to the normal, and an interference maximum is formed by those rays on a screen that is a great distance from the slits. Show that the angle θ2 is given by
where m is an integer.

- Plz plz no chatgpt pls will upvote .arrow_forwardYou want to determine if a new material created for solar panels increases the amount of energy that can be captured . You have acquired 15 panels of different sizes manufactured with different materials including the new material.You decide to set up an experiment to solve this problem .What do you think are the 3 most important variables to address in your experience? How would you incorporate those materials in your experiment?arrow_forwardNo chatgpt pls will upvotearrow_forward
- Why can't this be correct: &= 7m?arrow_forwardgive a brief definition of the word "paradigm" as well as an example of a current scientific paradigmarrow_forward7. Are all scientific theories testable in the commonly understood sense? How does this make you feel? How should you proceed as a scientist or engineer with this understanding?arrow_forward
- What is an an example of a hypothesis that sounds scientific but is notarrow_forwardWhat is an example of a scientific hypothesisarrow_forwardMultiverse is called a theory. It has been proposed to account for the apparent and uncanny fine tuning of our own universe. The idea of the multiverse is that there are infinite, distinct universes out there - all with distinct laws of nature and natural constants - and we live in just one of them. Using the accepted definition of the universe being all that there is (matter, space and energy), would you say that multiverse is a scientific theory?arrow_forward
- How is a law usually different than a theoryarrow_forwardA 1.50 mLmL syringe has an inner diameter of 5.00 mmmm, a needle inner diameter of 0.270 mmmm, and a plunger pad diameter (where you place your finger) of 1.2 cmcm. A nurse uses the syringe to inject medicine into a patient whose blood pressure is 140/100. Part A What is the minimum force the nurse needs to apply to the syringe? Express your answer with the appropriate units. View Available Hint(s)for Part A Hint 1for Part A. How to approach the question The force the nurse applies to the syringe can be determined from the fluid pressure and the area of the plunger. The minimum force corresponds to the patient's lowest blood pressure. Use the following equality 760mmofHg=1atm=1.013×10^5Pa760mmofHg=1atm=1.013×10^5Pa.arrow_forwardA 1.50 mLmL syringe has an inner diameter of 5.00 mmmm, a needle inner diameter of 0.270 mmmm, and a plunger pad diameter (where you place your finger) of 1.2 cmcm.
