Answer:
Sublimation is defined as the direct transition of a substance from solid state to gaseous state. The latent heat of sublimation is the sum of heat required for conversion from solid to liquid and heat required for conversion from liquid to gas. As in sublimation solid substance directly goes to gaseous state therefore, it is very difficult to find the components of latent heat of sublimation. This is the issue which arises in determining latent heat of sublimation.
On the other hand, when substance is melted it physically goes from solid to liquid. One can easily measure the heat required for this conversion.
Latent heat determination challenges differ between substances that sublime and those that melt. Sublimation involves a solid-to-gas change, typically under low pressure, making it difficult to contain the gas and measure accurate energy changes. In contrast, melting transitions from solid to liquid, with challenges in accurately measuring temperature change and ensuring complete melting.
When determining the latent heat of substances, different issues can arise depending on if the substance sublimes or melts. Melting is a transition from a solid to a liquid state, while sublimation involves a transition directly from a solid to a gas state.
One issue that might arise would be managing the environmental conditions. Sublimation often happens at low pressure, and ensuring a consistent low-pressure environment can be challenging. Also, because the substance is transitioning directly to a gas, it may be more difficult to accurately measure the energy change as some gas may escape during the process.
For melting substances, the issues are different as one is transitioning from a solid to a liquid state, and it's typically measured at atmospheric pressure. Accuracy in measuring the temperature change and ensuring the entire substance has completely melted are potential challenges.

Explanation:
The frequency of an electromagnetic wave is given by
where
is the speed of light
is the wavelength
For the light wave in this problem, the wavelength is
So by using the equation above, we find its frequency:
The frequency of light can be found by using the formula f = c ÷ λ, where c is the speed of light and λ is the wavelength. By substituting these values into the formula, you can calculate the frequency of light with a given wavelength.
When you are given the wavelength of light and asked to find its frequency, you would use the formula c = fλ, where c is the speed of light (3.00 x 10⁸ m/s in vacuum), f is the frequency, and λ is the wavelength. To find the frequency, we rearrange this formula to get f = c ÷ λ. Given the wavelength λ = 6.33 x 10^-7 m, we can substitute these values into the rearranged formula to find the frequency:
f = (3.00 x 10⁸ m/s) ÷ (6.33 x 10^-7 m)
By calculating the above equation, you will find the frequency of the light with the given wavelength.
