Assume Figure 38.1 was photographed with red light of a single wavelength λ0. The light passed through a single slit of width a and traveled distance L to the screen where the photograph was made. Consider the width of the central bright fringe, measured between the centers of the dark fringes on both sides of it. Rank from largest to smallest the widths of the central fringe in the following situations and note any cases of equality. (a) The experiment is performed as photographed. (b) The experiment is performed with light whose frequency is increased by 50%. (c) The experiment is performed with

- 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.

Case Study 1b - Cooper Carol has asked you to support the babies and toddler’s room educators this week. She has requested that you complete an observation on Cooper, who is a 10-month-old toddler. Carol wants to see how well you conduct an observation and is interested in how you manage to communicate in any observations made, using a strengths-based, non-judgemental, anti-biased approach, as this is a fundamental part of creating a supportive and respectful culture at Little Catalysts ELC.
