Question

Optical telescopes allow us to see further; they are able to collect and focus more light from distant objects than our eyes can alone. This is achieved by refracting or reflecting the light using lenses or mirrors. Refractive telescopes contain lenses much like those found in our eyes only much larger. inside the telescopes, light first reaches a primary lens. primary lenses are convey-rounded and are able to bend the captured light and aim it onto a secondary, focusing lens, responsible for focusing that light to produce a clear image of the object.

Reflective telescopes work in a similar way to refractors but by reflecting, instead of bending, light using curved mirrors. In both cases, more light captured in the primary stage means more power to see faraway and a more efficient focusing stage produces clearer images.

What happens if lenses capture little light?
A. It may damage our eyes
B. We hardly see distant objects
C. We will only see black shadows
D. We can see distant objects more clearly
E. We will get more detailed descriptions of the distant objects

D. Nur · Accepted Answer

Jawaban untuk soal ini adalah B. We hardly see distant objects.

Soal ini menanyakan hal yang akan terjadi jika lensa pada teleskop optik menangkap sedikit cahaya.

Untuk menjawab soalnya, perhatikan kalimat akhir di paragraf 2 berikut!

"..., more light captured in the primary stage means more power to see faraway ..."

Arti
"..., lebih banyak cahaya yang ditangkap lensa utama, itu tandanya akan ada lebih banyak kemungkinan untuk melihat objek jauh ..."

Dilihat dari arti kalimat tersebut, dapat disimpulkan bahwa hal yang akan terjadi jika lensa menangkap sedikit cahaya adalah 'objek jauh akan sulit dilihat'. Ini sesuai dengan opsi  B.

Jadi, jawaban untuk soal ini adalah B. We hardly see distant objects.
