Which uses the refractive properties of light to separate it into its different wavelengths?
miss Akunina [59]

A). No.  A mirror doesn't separate light into its different wavelengths.

B). No.  Light doesn't separate into its different wavelengths when it
goes, say, from glass into water.

C). No.  When light goes through your glasses, it doesn't separate
into its different wavelengths.

D). Yes !  When sunlight shines into droplets of water in the atmosphere,
it comes out separated into its different wavelengths.  When we see that
happening in the air in front of us, we call it a "rainbow".

6. What is the bulk modulus of oxygen if 32.0 g of oxygen occupies 22.4 L and the speed of sound in the oxygen is 317 m/s?
Arlecino [84]

Answer:

\boxed{\sf Bulk \ modulus \ of \ oxygen \approx 143.5 \ kPa}

Given:

Mass of oxygen (m) = 32.0 g = 0.032 kg

Volume occupied by oxygen (V) = 22.4 L = 0.0224 m³

Speed of sound in oxygen (v) = 317 m/s

To Find:

Bulk modulus of oxygen

Explanation:

\sf Density \ of \ oxygen \ (\rho) = \frac{m}{V}

\sf \implies Bulk \ modulus \ of \ oxygen \ (B) = v^{2} \rho

\sf \implies B = v^{2}  \times\frac{m}{V}

\sf \implies B  =  {(317)}^{2}  \times  \frac{0.032}{0.0224}

\sf \implies B  =  {(317)}^{2}  \times 1.428

\sf \implies B  = 100489 \times 1.428

\sf \implies B  = 143498.292 \: Pa

\sf \implies B   \approx 143.5 \: kPa
