One property of light that makes it possible to record the image of an object with the camera

Answers

Answer:

Reflection

Explanation:

Reflection is the property of light in which when a ray of light hits a smooth surface, it bounces back in the direction in which it came from. If i is the angle between the normal to the surface and the incident ray, and r is the angle between the normal and reflected ray, the law of reflection states that the angle of incidence equals the angle of reflection. That is, i = r.

So, to record the image of an object with a camera, one property of light that makes that possible is reflection because, the incidence rays form an image of the object in the camera, while the reflected rays reflect the image so that it is visible to the eye.

Which graphic file format would you choose if you needed to make an animated graphic for a website? ai

png

gif

py
please help

Answers

Answer:

The answer to this question is given below in the explanation section.

Explanation:

The correct option for this question is gif.

Gif is a series of images that are used as animated graphics for a website. A gif is the file format of an animated image. You may have seen many animated images on websites like stickers etc.

other options are not correct because:

ai: is adobe illustrator file format

png: png is an image file format but not for an animated image

py: py is a file extension of the python file.

When it comes to creating animated graphics for a website, the most commonly used file format is GIF (Graphics Interchange Format).

The correct option is C.

GIF files support animation by displaying a series of frames in a sequence. Each frame contains a different image, and when played in quick succession, it creates the illusion of movement.

GIFs are widely supported by web browsers and can be easily embedded in web pages. They are particularly popular for creating small, simple animations such as icons, logos, or short loops. GIFs also support transparency, allowing you to have parts of the image appear transparent or semi-transparent, which can be useful when integrating the animation into a website design.

On the other hand, the other options mentioned in the question are not suitable for creating animated graphics for a website.

- AI (Adobe Illustrator) is a file format used for vector graphics, typically created and edited in programs like Adobe Illustrator. While AI files can contain animations, they are not commonly used for web animations.

- PNG (Portable Network Graphics) is a file format that supports static images with high quality and transparent backgrounds. However, it does not support animation by default.

- PY is a file extension used for Python programming language files. It is not a file format suitable for creating graphics or animations for websites.
