Find the dimensional formula for Planck's constant (h).

Explanation

To find the dimensional formula for Planck's constant (h), we can start with the relationship between energy (E), frequency (ν), and Planck's constant. The relevant equations are:

1. \( E = h \nu \)
2. \( E = \frac{hc}{\lambda} \)

Where:
- \( E \) is energy,
- \( h \) is Planck's constant,
