Indonesia, Bali, Denpasar :D

Kita tinggal di Indonesia, tepatnya Pulau Bali, di daerah Kota Denpasar, yang penuh dengan hal-hal yang menarik. :)  Jadi, kita sebaiknya menggunakan Bahasa Indonesia yang baik dan benar. Boleh juga kalian menggunakan Bahasa Daerah kalian, tetapi harus sopan dan tidak menggunakan kata-kata kasar. Sekarang aku akan mencoba memberikan sensasi dengan menggunakan 2 bahasa di blog ini yaitu Bahasa Indonesia dan Bahasa Inggris. Hahaha...

Kalo kalian penasaran dan ingin meminta terjemahan blog ini, baik ke dalam Bahasa Indonesia kita tercinta, ataupun ke dalam Bahasa Internasional (Bahasa Ingris), kalian dapat menghubungi atau mengkonfirmasikan lewat comment ataupun juga lewat Chat Box untuk chat denganku. :D

Sekarang aku ingin memberitahu kalian Pulau Bali kita yang tercinta ini. x)

Pulau Bali merupakan pulau yang terkenal akan pariwisatanya terutama pantai-pantainya yang sudah merupakan kunjungan wajib bagi turis-turis asing yang berkunjung ke Bali kita. Selain itu, Bali juga mempunyai keunikkan tersendiri dari segi kebudayaan. Kebudayaan kita unik, lo! :)

Dan yang paling ditunggu-tunggu para turis baik domestik ataupun turis asing adalah makanan khas kita seperti babi gulin atau suckling pig, lawar, ayam betutu, dan lainnya. 

Tempat pariwisata Bali juga unik dan menarik seperti Pantai Kuta, Pantai Sanur, Pantai Double Six, Gua Lawah, Pura Besakih, Tanah Lot, Sangeh, dan masih banyak tempat yang lainnya.. 

Kalau kalian mau membeli oleh-oleh dari Bali, kalian juga bisa datang ke Joger, Jangkrik, Erlangga, atau Krisna. Itu semua merupakan tempat baju-baju khas Bali, sandal, pin, makanan, souvenir, dan juga bermacam-macam barang-barang Bali yang unik. 

Yeah.. sampai di sini dulu cerita tentang Pulau Bali kita ini.

Tunggu artikel tentang Kota Denpasarnya yapz!!

Optical Instruments

Optical Instruments

An optical instrument either processes light waves to enhance an image for viewing, or analyzes light waves (or photons) to determine one of a number of characteristic properties.

The examples of optical instruments are:

• Eye
• Camera
• Lup
• Microscope
• Telescope
• Projector

Eyes

Eyes are organs that detect light. Different kinds of light-sensitive organs are found in a variety of animals. The simplest "eyes", in even unicellular organisms, do nothing but detect whether the surroundings are light or dark, which is sufficient for the entrainment of circadian rhythms and may allow the organism to seek out or avoid light, but hardly can be called vision.

Part of Eye

The part of eye are :
-Retina
-Cornea
-Iris
-Lens
-Pupil
-Eye nerve

• Retina: retina has function to arrest shadow which mouldable by eye lens
• Cornea: cornea has function to receive light and continue light and protect eye lens from feather.
• Iris: the iris has function to give color to eye.
• Eye Lens: eye lens has function to make thing shadow.
• Pupil: pupil has function to organize light intensity.
• Eye Nerve: eye nerve has function to continue signal from retina to brain.

Eye Accommodations

The purpose of the optics of the mammalian eye is to bring a clear image of the visual world onto the retina. Because of limited depth of field of the mammalian eye, an object at one distance from the eye might project a clear image, while an object either closer to or further from the eye will not. To make images clear for objects at different distances from the eye, its optical power needs to be changed. This is accomplished mainly by changing the curvature of the lens. For distant objects, the lens needs to be made flatter, for near objects the lens needs to be made thicker and more rounded.

Eye Diseases

There are 3 kind of eye diseases:

-Near sighted (Miopi)
-Long sighted (Hipermetropi)
-Old eye (Presbiopi)

• Miopi: can not see object with far distance in clearly.
• Hipermetropi: can not see object with near distance in clearly.
• Presbiopi: can not see object with far and near distance in clearly. Presbiobi usually occurs in elderly! 

Camera

A camera is a device used to capture images, either as still photographs or as sequences of moving images. If there is iris in eye, in camera there is diaphragm.
Camera consist of convex lens which can arranged for focus real shadow in order to fall to film.
Characteristic of shadow in film is obvious, capsize and smaller.

Lup

Lup is lens which use to see small thing become bigger and clear.

Microscope

A microscope is an instrument for viewing objects that are too small to be seen by the naked eyes. 

Projector

Projector is optical instrument that has function to projecting picture to screen until the shadow of the thing appear bigger and more clear. Projector is divided by 2, there are episcop and diascop. Episcop is projector that has function to projected untranslucent object.
Diascop is projector that has function to projected translucent object.

Examples of diascop:
-Slide Projector
-Film Projector
-Overhead Projector
