A wave has an energy of 1.5x10^3 J. Find its wavelength?
weqwewe [10]

Answer:

1.3 × 10⁻²⁸ m

Explanation:

The equation relating the energy (<em>E</em>) and the wavelength (λ) of a wave is  

E =\frac{hc}{\lambda}

where <em>h</em> = Planck’s constant and <em>c</em> = the speed of light

\lambda =\frac{6.626 \times 10^{-34}\text{ J}\cdot \text{s} \times 2.998 \times 10^{8} \text{ m} \cdot \text{s}^{-1}}{1.5 \times 10^{3} \text{ J}} = 1.3 \times 10^{-28}\text{ m}

How does specific heat and heat transfer relate to remote islands
Vladimir79 [104]
Heat capacity is the ability of a material to store heat, higher the heat capacity higher the amount to heat stored by the material. Heat transfer usually varies inversely with heat capacity, i.e heat transfer will decrease with increase in heat capacity and vice versa. Thermal diffusivity is the ratio of thermal conductivity to the heat capacity, it says how fast (or slow) heat is transferred inside a material. Usually thermal diffusivity is directly proportional to the heat transfer rate, since heat capacity appears on the denominator, heat transfer is inversely proportional to the heat capacity.

Why is looking through water different than looking through air?
morpeh [17]
Looking through water has a curved effect. When the light travels through it, the transperancy is different. If you stick a pencil into a half filled glass of water you will see that it is optimised but the direction is different.
