please help me answering this questions I just need the answer I don't need the full solution. I have 30min left

Question 45 (1 point) Listen Pattern A, an interference pattern viewed on a screen using a monochromatic source, is changed to pattern B. Both are shown below: Pattern A Pattern B Which of the following changes could explain the change in the pattern? They are both double slits, but Pattern A is made with lower wavelength light. They are both double slits, but Pattern A is made with higher wavelength light. Pattern A is a single slit and Pattern B is a double slit. Pattern B is a single slit and Pattern B is a double slit.Question 32 (1 point) Listen Four charged spheres, A, D, P and T are arranged as shown below. Sphere A has a charge of +4.5x10 4 C, sphere D has a charge of -6.2x10-4 C, sphere P has a charge of +7.5x10-4 C and sphere T has a charge of -1.5x10-4 C. 20 cm D T - 20 cm Which two spheres exert the smallest force on each other? A and P OP and DListen Which of the following diagrams most accurately depicts the field between two positively charged point charges? O + + O undefined + +Question 46 (1 point) Listen Light of wavelength 355 nm passes through a single slit and diffracts, producing an interference pattern.
