What is the wavelength of radiation that has a frequency of 7.2×10^11 s−1 ?

Airida [17]

Explanation:

It is known that relation between wavelength and frequency is as follows.

$\lambda = \frac{c}{\nu}$

where, $\lambda$ = wavelength

c = speed of light = $3 \times 10^{8} m/s$

[/tex]\nu[/tex] = frequency

It is given that frequency is $7.2 \times 10^{11} s^{-1}$ . Hence, putting this value into the above formula and calculate the wavelength as follows.

$\lambda = \frac{c}{\nu}$

$\lambda = \frac{3 \times 10^{8} m/s}{7.2 \times 10^{11} s^{-1}}$

= $0.416 \times 10^{-3} m$

or, = $4.16 \times 10^{-4} m$

Thus, we can conclude that wavelength of given radiation is $4.16 \times 10^{-4} m$ .

How many moles of carbon atoms are present<br> in 5.4 moles of glucose?<br> Answer in units of mol.

Delvig [45]

Answer:

32.4 mol

Explanation:

Given data:

Number of moles of C atom present = ?

Number of moles of glucose = 5.4 mol

Solution:

Glucose formula = C₆H₁₂O₆

There are 6 moles of C atoms are present in one mole of glucose.

In 5.4 moles of glucose:

5.4 mol × 6 = 32.4 mol

Give an example of how you could use different reference frames for the same motion.

RUDIKE [14]

Answer:

Motion is defined as a change of position. How we perceive motion depends on our frame of reference. Frame of reference refers to something that is not moving with respect to an observer that can be used to detect motion.
