Short Answer 
The riddle hints at “light” through clues that suggest it moves without physical form and is connected to sound and sunlight. Analyzing the phrases leads to the conclusion that light is essential for visibility while remaining invisible itself.
Step 1: Understand the Clues
The riddle provides several clues that hint towards the answer. Key phrases include “I move without legs” and “I rise without wings”, indicating a concept that can operate independently of physical forms of movement. Analyzing these phrases helps to eliminate living beings and directs us towards non-physical entities.
Step 2: Analyze Related Characteristics
The riddle describes something that can be heard in silence and is linked to sunlight. The line “you can hear my voice in silent things” suggests it has an impact even when it’s not physically visible. Coupled with “I follow you in sunlight, but disappear at night”, this narrows our focus to elements connected with light.
Step 3: Conclude with the Answer
Considering all the clues, we arrive at the conclusion that the answer is light. It is necessary for visibility—“Without me, you can’t see”—yet it remains invisible itself. Therefore, light perfectly fits all the descriptions provided in the riddle.
