Question

physics

1. What is diffraction? How does diffraction affect the appearance of an image?

2. Amount of diffraction depend on how wavelength of the light compares to the hole it’s going through (how?)

3. Where did cameras originate? (Camera Obscura)

4. What invention revolutionized camera technology? (film)

5. What are the four components of a camera (camera back, lens, diaphragm, shutter) How do Cameras Work? (

6. What are depth of focus and depth of field? How are they imposed by the bending of light from lenses?

7. How does narrowing or widening the diameter of a lens affect depth of field?

8. Can you tell the difference between photos with high or low depth of field?

9. What are the different types of camera (fixed focus, view camera, single lens reflex (SLR) and digital)

10. What are the advantages and disadvantages of the different camera types?

11. Understand well how the lens equation works when used to describe the human eye or a camera, and what the different components mean! 1/f = 1/xo + 1/xi

12. Understand how rays entering a lens from far away differ from those entering from a nearby object! How is this reflected in the lens equation?

13. How does the focal length of a lens influence the size of an image and its magnification?

14. What is an f-number? How does it change with differing focal length and/or diameter of a lens?

15. How does changing an f-number affect the depth of field?

16. How does f-number depend on the area of a lens?

17. How are f-numbers arranged on the f-number sequence?

18. How do we combine f-number with the shutter speed to influence the amount of light entering a lens?

19. What is the exposure, and how does it depend on the intensity of light, exposure time and area of the lens? (Exposure = intensity × area × exposure time)

Answer 1

here,

Diffraction in simple terms is a phenomena that occurs with light when it interacts with an obstacleor passes through slip.

More diffraction much blullier image or you can say less sharpness on image.
