1. As the wavelength decreases, the frequency
1 answer:
Answer:
The frequency will increase
Explanation:
- Wavelength and frequency are inversely related such that waves with longer wavelength tend to have lower frequency and those with shorter wavelength have higher frequency.
-
- For example, gamma rays have a shorter wavelength but high frequency while radio waves have longer wavelength but have a low frequency.
- The product of wavelength and frequency gives the speed of the wave.
- Velocity = frequency × wavelength
- Wavelength is measured in meters while frequency is measured in Hertz.

Mass of the water is 2.63 g.
<u>Explanation:</u>
Mass of the water, m = ? g
Temperature, ΔT = 15 °C
Heat absorbed, q = 165 J
Specific heat capacity, c = 4.18 J / g °C
q = m × c × ΔT
Now, we have to find the mass of the water by rewriting the above equation as,
m =
Now Plugin the above values in the equation as,
m =
= 2.63 g
So the mass of the water is found as 2.63 g.
