(a) To determine The average speed of the insect. Explanation Write the equation for the average speed. s ¯ = d Δ t (I) Here, s ¯ is the average speed, d is the distance travelled and Δ t is the time taken for the motion. Write the expression for the distance travelled by the insect. d = l + w Here, l is the length of the pool and w is the width of the pool. Put the above equation in equation (I). s ¯ = l + w Δ t (II) Conclusion: Substitute 27 m for l (b) To determine The magnitude of the average velocity of the insect.

Fresnel lens: You would like to design a 25 mm diameter blazed Fresnel zone plate with a first-order power of +1.5 diopters. What is the lithography requirement (resolution required) for making this lens that is designed for 550 nm? Express your answer in units of μm to one decimal point. Fresnel lens: What would the power of the first diffracted order of this lens be at wavelength of 400 nm? Express your answer in diopters to one decimal point. Eye: A person with myopic eyes has a far point of 15 cm. What power contact lenses does she need to correct her version to a standard far point at infinity? Give your answer in diopter to one decimal point.

Paraxial design of a field flattener. Imagine your optical system has Petzal curvature of the field with radius p. In Module 1 of Course 1, a homework problem asked you to derive the paraxial focus shift along the axis when a slab of glass was inserted in a converging cone of rays. Find or re-derive that result, then use it to calculate the paraxial radius of curvature of a field flattener of refractive index n that will correct the observed Petzval. Assume that the side of the flattener facing the image plane is plano. What is the required radius of the plano-convex field flattener? (p written as rho )
