What factors influence the symmetrical interference pattern when a wave passes through two slits? Draw and label a refraction diagram for a wave slowing down. Draw and label a refraction diagram for a wave undergoing total internal reflection. What are the two main theories regarding the nature of light? A pin hole camera that is 16.0 cm long produces a 7.5 cm tall image of a 5.6 m tall object. What is the distance of the pinhole camera to the object? (11.9 m) A 3 cm card is placed 25 cm in front of a light source. If a 30 cm shadow is generated on the wall behind the card, how far is the card from the wall? (225 cm) Galaxy XX is located 6.5 × 10 22 km from Earth. How many light-years away is the ga1axy? (6.87 billion light years) If the rotating mirror in Michelson's mirror experiment rotates at 83.3 Hz, how far away must the fixed mirror be located in order to give a successful experiment? (225 km) If the fixed mirror in an eight-sided Michelson's mirror experiment is placed 65 km away from the rotating mirror, what is the frequency for the rotating mirror in order to give a successful experiment?
