Great question, but the answer kind of depends on how big the fireworks are and how close you are to the action. Bring both lenses and don't be afraid to swap them and change focal lengths through the show! If you are returning to a show you've been at in the past, try to rememb...
An object is placed in front of a concave mirror of focal length 20 cm. The image formed is three times the size of the object. Calculate two possible distances of the object from the mirror? View Solution An object is held in front of a concave mirror of focal length15cm. The image...
Ten years ago students studying the diffraction pattern produced by an illuminated slit did not know that the same method of procedure would enable them to calculate the directional characteristics of an underwater sound signaling apparatus. Some of the students who had studied the principles, ...
How to convert hours to seconds with a formula What is the volume of a cone with a radius of 3cm and height of 5cm? What is the base metric unit for measuring mass? A 1145 gram block of wood has the measurements of 11.2 cm x 12.1 cm X 13.6 cm. Calculate the density of the wood...
How to calculate work on an inclined plane Explain how the focal length of both concave and convex lens is calculated. What quantities are needed to calculate angular momentum? Provide the formula for calculating the acceleration of a motor given the moment of inertia and the accelerating torque....
diffuse reflection and spherical aberration easier to understand. Additionally, terminology has been refined, with clearer explanations of virtual images, focal points, and optical axis behavior. While the core physics remains unchanged, the presentation is more accessible and engaging, making the content...
BIO A person can see clearly up close but cannot focus on objects beyond 75.0 cm. She opts for contact lenses to correct her vision. (c) What focal length contact lens is needed, and what is its power in diopters? 348 Textbook Question ...
So yes, there is light loss … but that’s the idea with the pre-flash. The camera will now be able to calculate what the actual main burst of light should be, for correct exposure. Reply
Charles Deehr, a professor emeritus in physics at the University of Alaska Geophysical Institute, says: “These are interference fringes due to the parallel faces of the filter and to the narrow spectral emission at 5577 Angstroms in the aurora. That green, atomic oxygen emission line is the ...
