Question 7 2 points How Did I Do? (a) What is the intensity of a 4.5 mW laser pointer beam with a diameter of 1.5 mm? (These are typical characteristics of inexpensive laser pointers.) I= Number Units (b) What is the ratio of this intensity to the average intensity of sunlight at the Earth's surface (700 W/m²)? laser Isun Number (Considering the damage that looking directly into the sun can cause your eyes, imagine the implications if the laser beam entered your eye! This is why you generally need to be careful with lasers.)
