Answer:
A
Explanation:
The amplitude of a sound wave determines its loudness or volume. A larger amplitude means a louder sound, and a smaller amplitude means a softer sound.
Answer:
Index of Refraction = 1.52
Explanation:
The index of refraction or the refractive index is given as:
Index of Refraction = Sin i/Sin r
where,
i = angle of incidence
r = angle of refraction
In this case of karo syrup, we have the following data:
i = angle of incidence = 30°
r = angle of refraction = 19.24°
Therefore, substituting these values in the equation, we get:
Index of Refraction = Sin 30°/Sin 19.24°
Index of Refraction = 0.5/0.3295
<u>Index of Refraction = 1.52</u>
Hence, the refractive index or the index of refraction of the Karo Syrup is found to be <u>1.52</u><u>.</u>
