This is a phenomena scattering of wave during ______________ .

Blue colour is scattered _______ compared to the ______ colour.

• sunset, more, yellow

• sunset, less, red

• the day, more, yellow

• the day, less, yellow

At noon the sky appears blue as

• light is least scattered

• all the colours of the white light are scattered away

• blue colour is scattered the most

• red colour is scattered the most

Why the sky look blue during midday and red during sunset

• Reflection of light

• Refraction of light

• Dispersion of Light

• Scattering of Light

Why does scattering of light occur?

• Light rays are blocked and reflected to all directions by the clouds or particles in the air

• Light rays are blocked and reflracted to all directions by the clouds or particles in the air

• Light rays are passing through and refracted to all directions by the clouds or particles in the air

• 
• 
• 
• 

Here is an example of fine particles in the atmosphere that scatter light.

(More than one answer)

• Dust

• Water droplet

• Leaf

• Gas molecule

The blue sky and the red sky at dusk are natural phenomena caused by the scattering of light

• BETUL / TRUE

• SALAH / FALSE

Pada waktu senja, cahaya matahari bersinar secara _______./

At dusk, sunlight shines _______.

• lurus / straight

• terang / bright

• mengufuk / horizontally

Why does the Sun appear red at sunset?

Mengapakah matahari kelihatan merah ketika matahari terbenam?

• Red light is the least scattered and travel the longer distance.

  Cahaya merah paling kurang diserakkan dan bergerak dengan jarak yang panjang.

• Red light is the most scattered and travel the shorter distance.

  Cahaya merah paling banyak diserakkan dan bergerak dengan jarak yang pendek.

• Red light is the least scattered and more blue light are scattered.

  Cahaya merah paling kurang diserakkan dan lebih banyak cahaya biru diserakkan jauh.

• All the components of white light are absorbed by the atmosphere except red light.

  Semua komponen cahaya putih diserap oleh atmosfera kecuali cahaya merah

______________ light is scattered the most by the suspended particles because it has a ___________ wavelength.

• blue / long

• red / long

• blue / short

• red / short
