How does a camera work

🤔 How it works ……..

How does a camera work? . 📷📸

Camera lens takes all the light rays bouncing around and uses glass to redirect them to a single point, creating a sharp image. When all of those light rays meet back together on a digital camera sensor or a piece of film, they create a sharp image.

The LENS gathers light from the selected image and focuses the light on to the medium.

The IRIS or diaphragm controls the amount of light that reaches the medium.

The SHUTTER is a door or gate that opens to allow selected light to reach the medium and closes after a user determined time.

The MEDIUM is the material or device where the light is transferred into a recorded image. With film cameras this is a film of acetate with layers of gelatin immpreated with silver halide particles

😳Why❓❓❓

Why we can’t hear,👂🏻 when we sleep.?

The mind🧠 disconnects itself from the sense organ when we are in deep sleep.😪 Our mind as well as your brain are not active. Bcz our conscious mind is asleep and our subconscious is always wide awake.
So whatever noises happens during our conscious is “asleep” our subconscious will pick it up and we might remember the noise or sound we heard when we were sleep. if we heard it again while we’re awake it will trigger you subconscious mind .

When we are in deep sleep. If somebody is yelling at us calling by names. We don’t show any reaction. The mind is not there to interpret our ego- our personality is not there. When we come back to waking state, our mind and body begins to appear in our consciousness.

But again here a question arises; When you are not able to hear anything during sleep, how does our brain wake up when hearing the alarm sound?

when we are awake there is a link between the auditory centre of the brain and the higher centres of our brain that process and understand this auditory information and then respond to it. When we go to sleep, this becomes delinked.

A really loud sound, however, will provide enough voltage and links and will wake us up. Other sounds that have very strong associations in our memory, e.g. our ringtone, alarm tone or a doorbell, may also provide enough voltage in the circuit even if they’re a bit quieter.
